No, not backwards, just interdependent. It's a Catch-22 situation.

That wasn't what Zenon said. He said "if you assume that any installations
in space are _eventually_ Earth-centered, i.e., their only end purpose is to
bring something useful down here", your argument was about INITIALLY being
Earth centered, which we would all stipulate without contest. I think it is
fairly evident that the whole point of being there initially would be
Earth-centric, but I think it is equally evident that as the off-Earth
presence of people increases, more and more off-Earth market will develop.
It really doesn't matter which it is or even in what proportion, as long as
there is _enough_ industry of the right kinds to make building a starship
economical and practical.
We have already discussed the other point here several times. It is most
unlikely that the first ships to go out will be anything _but_ government
funded, for the same reasons. Until we get there and find out what is there,
there will be no economic reason to drive a private mission to or presence
at another star.

I doubt that also, but stranger things have happened.
