We are roughly in the middle of the large and small scales I listed in the OP. You seem to want to argue about the large and small scales I listed as not being necessarily absolutes. I can't work with what we don't know. The scales I have listed are what we know and it's not as you suggest because we can see them. So, in that sense you are wrong. We haven't seen a Planck length or even measured anything smaller than 10^-18. Additionally, I find it helpful and interesting to have those benchmarks to help gain perspective of just how small an atom is, a nucleus is, etc. If you don't, that fine as well.
