Not completely true. Space access would have been cheaper under a free
market regime from the start. Recall where Goddard got his funding from.
But be that as it may, the problem is not that space access is expensive,
but that the governments subsidize space programs to begin with. This made
private launches untenable. Surely, government programs cost more, BUT the
whole cost is not passed on to Hughes or other users of government launch
vehicles. Instead, the taxpayer funds that.

The main point is: it's a proven technology. Ergo, you don't have to spend
lots on R&D to come up with your super special design. A secondary point
is: reusability does NOT guarantee efficiency. The American Space Shuttle
is proof that reusable vehicles can cost more to fly and maintain. Remember
also, if you're making a disposable launch vehicle, then you need not worry
about a lot of maintenance problems.

I don't mean that at all. What I mean is that the Biosphere concept has got
to be put into the context of merely one plan to colonize and exploit space.
I would rather look for a way to get the resources that will be spent in
other ways, such as, e.g. (and this is just an example; I'm trying to break
people out of the Biosphere idea), oxygen from Moon rocks, than worry about
a delicate ecosystem recycling my oxygen.
As for economic rationales, there are plenty. Power from orbiting
satellites is an oldie. Manufactured goods from space is another. Moving
pollution creating industries to space is another. Moving dangerous biotech
and nanotech research off the Earth. Tourism. Etc.
