ambi, CubeStats come to mind. I know someone incidently who is building one (all the big schools are doing it these days). They're affordable but hardly able to do much unfortunately. CubeSats are essentially subsidized by schools and other organizations, which is why they're fairly cost effective (I think Yarrow left out a digit in his number, though!). Getting into orbit is not as easy as it sounds, because you have to reach near escape velocity (it's not a matter of height but of speed). 25k mph is nothing to laugh at, and getting any piece of matter up to that speed is quite difficult. I do not believe (though I could very well be wrong) that any civilian has made a rocket reach orbit (actual orbit, not that pathetic 100 km 'definition' of space), and only a few corporations have achieved the goal.
There's one thing I should point out though, that fits well here at least with regards to anarchy. Iain Banks made the intelligent if not intuitive observation that space does not facilitate trade or markets so much self-sufficiency and high technology.
A case in point is that if you could do He3 fusion, then you'd be able to do pB11 fusion (which incidentally produces He3). B11 (Boron) being comparatively common in the universe compared to He3. And having a much lower aneutronic profile (produces much less neutrons than He3), which helps the fusion reactor last a lot longer (neutrons are bad for, erm, matter stablity).
You can think of any example of 'trade' or 'exchange' in space and I can show how it just ... doesn't work. Surviving in an environment like space requires, absolutely requires, technologies that mitigate scarcity as much as possible, so that you don't die because someone cuts off the air because you can't pay for it (an old argument I had on ASC was about this very idea!).
I am a leader, but you will not follow me.
