Not in the least, and quite dishonest of you to say so. I most certainly recognise the facts as apply today, and I most certainly recognise that at this time and probably within the near future, it is impossible for us to achieve with present technology. Where I differ from your "stick in the mud" attitude, is that I recognise that improvements and technologies will improve with possibly new discoveries in time. And of course without any progress in any warp travel technology, a generation ship is always an option. And I have often mentioned with these disaster scenarios you seem so focused on, that the stars being our destiny, does certainly depend on how we overcome our Earthly problems also. So again putting it all in a nut shell, we will return to the Moon, [and so we should] and we will send man to Mars, [as also we should] just as eventually we will also mine Asteroids. Startreking probably not in the immediate foreseeable future, but as long as we can survive our Earthly follies, in time that also will eventuate.
