Wes, I'm not sure how useful this will be for you, but please read and consider the whole before replying. My whole reply culminates in the question at the end -
Okay read, understood, but I have to respond piecemeal as learning to communicate with someone is to me, enhanced by doing so. In this particular case, it's because our approach to the framing of the problem seems to differ dignificantly. I shall attempt to at least put a slight dent in the differences. (and yes 'dignificantly' was a typo, but I decided I like it better than the real word in this case).
Then the "seems" is all there is.
Epistemelogically, yes. This is crucial IMO, as "what we 'know' is what we 'are' in a very strong sense. More technically in my funky little perspective, what we "know" comprises a sort of supportive structure, a framework if you will; for self (ego).
Seems is more specifically "all that can be
known in an absolute sense". I mean this as in: "the ego of a perspective is the only entity directly privvy to its input and is uniquely and necessarily qualified to report on the status of said perspective (the particulars don't even have to make sense in another context for this to be true). The report and the status are the same thing, from the reference frame of the ego making the report.
If the "seems" is all there is, how then can we possibly speak of anything beyond it - the objective? We can't.

Of course we can. We just can't KNOW if that's what we're speaking of, we can only claim its utility in the context of our own value function (instantaneous evaluation of value as applied in a mind at whatever time). Utility however, is the thing... as really it's integral to "how things seem to me" - again this is one of those that you don't have to consciously do for it to get done.
In light of this, I think it would be better then to speak of utility only. Utility necessarily implies that we are talking about what is useful or relevant within a particular context. Adding issues of "objectivity" and "subjectivity" is a pleonasm then, but which significantly complicates matters.
But as I see it, it is the difference between "objectivity" and "subjectivity" that allows for the possiblity of utlity in the first place. If there is no such thing as the subjective, there exists no context - the unobserved universe. It just IS, and cannot be spoken of. Since I'm here to talk - and it seems that it's the fact that I am a subjective creature that allows me to do so - the issues of objectivity are not intentionally "added" for any affect, but are terms used to model the problem as closely as to how "reality" seems to me in my best attempt to recognize it.
How can you know it objectively exists, if all that a person can have or know is subjective (as you admitted earlier)?
Indeed. I cannot know if it objectively exists, but I can know the idea that it does to be of enough utility to accept (assume) for whatever context or amount of time suits my utility.
It seems to me you are positing the existence of objective reality so as to work out some problems that emerge if we presume that subjective reality is all there is.
Well... the utility of the idea is significant in my comprehension of how all this stuff works. My usage of "objectively reality" is quite simple: "a common medium". IMO, it follows quite closely from the assumption "I am", which IMO is equivalent to "I exist" which directly implies as I see it "a means for which the acts to be accompished" such as the simplest solution "a common medium".
This is so if we accept that an individual objectively exists.
Which I do per the explanation above. Would you disagree that you objectively exist? If so, I would disagree with you as ask how you think I came up with your questions for you though it seemed to you that you did it, unless of course you disagree that you think you did it - at which point I would have to question your honesty or sanity.
Sure - but I don't have to see it this way.
Of course. I don't think you have to unless you recognize it as truth that is of positive utility to your value function. Then you have to because you did so.
I can read and reply, but I don't have to use the notions of "subjective" and "objective".
No you don't have to - no one is forcing you, as that's not particularly easy to do, nor would it be of any use to me. What you have to do, is figure out if the idea has any merit whatsoever to you, and if you decide not to jack with it, you established the merit.
Not to be naive - but my point is that there are more ways possible of how to understand what is going on.
Sure there are always more ways. Which is rational? Which is effective? Which appeals to your emotions? Which wins? I'm telling you what wins for me now. It might help or hinder our respective content and quailty of "wins" in this context. The thing is neither of us has a choice - if we're as honest as we can be with ourselves, as to what "wins" for us.
We seek what we value, that is our function. It can be observed directly in deed/thought. However, sort of like photons perhaps, the act of observing it changes its appearance.
That seems rather absolute.
Otherwise it is pointless to speak of the distinction "objective" and "subjective".
Is it pointless to distinguish between yin and yang? In what context? It's certainly not pointless in the context they themselves establish. The manner in which I relate to my environment establishes its own context too.
If it is "indeterminate" or "both", then the distinction between "objective" and "subjective" is superfluous.

Perhaps to you, at the moment sure. Probably to most people at most moments, yes. But at the moment I invoke it, it is not, as it rings to me as necessary as established by the manner in which I relate to my environment. Hopefully I explained well enough above why I find it relevant.
Considering everything said above - let me ask you this:
If you refrained from using the terms and concepts of "subjective" and "objective", but kept the term and concept "utility", what would change for you?
Well as I said above, I think it is the very distinction in question that defines or without it, could not allow the capacity to make distinctions.
