You still need downlinks with this. You could have some base stations run by amateurs, but that paints a target on their backs in a similar way running a Tor node already does.

It would probably be easier to leave an exit node on a barge in international waters to be honest.

You need approval to launch satellites. Plus a stupid amount of money.

Only 11-year-old Libertarians think this way. "Circumventing sovereignty" is the surest way to destruction. Anyone who stands outside the protection of a legitimate sovereign power will be immediately destroyed by a real country. If you fly your shit out in space and declare your satellites to be independent of any flag, I am sure that they will all promptly disappear due to mysterious causes. Likewise, if you believe that you will simply move to a remote floating platform where you declare independence, you will soon discover what the U.S. Navy is for.

They will most likely be owned by a company that still under a jurisdiction on earth.

How would they get network? Ground stations would just blacklist them.
