Space is extremely regulated, SpaceX just gets permits approved to do anything they want because they’re extremely cooperative with the US military and CIA.

Rocket Lab is a private rocket company that launches from New Zealand, but part of the company is in the US so they still have to get an FAA license to launch from any country. No matter where SpaceX goes they would need FAA and FCC licensing.

With Glock handguns specifically it’s easy to shove something in the back to block the little catch that stops it from being fully automatic, and right now it’s slightly easier to 3d print the right size piece of plastic than do it with a dremel. Some activists wanted to ban Glocks, but Glock is a big corporation so NY politicians warped it into a 3d printer ban while acting like they this is what you asked for.

And it’s vice-signalling to billionaires because Luigi supposedly had a 3d printed gun.
