I get what you're trying to say, but the paperwork isn't just to not get arrested. It's also to make sure your rocket doesn't flatten a building when it comes down uncontrolled, doesn't hit an airplane on the way up, doesn't crash into any other spacecraft in orbit, and doesn't turn into yet another piece of untracked space debris cluttering Earth orbit.
None of which gets in the way of actually making a rocket or launching it though, as unlike for example cars or guns everyone builds and launches their own anyway. Well, 99% of the time anyway.
