Maybe I'm reading too much into this, but this kind of sounds like a technofascist trial balloon to push for the privatization of the US military. The implication being

Why can't our nation's air industry not simply buy the right to fly through no-fly zones? This is deep state oppression curtailing YOUR freedoms to go where-ever you please. If we just privatize military research and production it will be more productive (SpaceX is better than NASA) and American (a big state is communist; those military officers that don't want to invade Canada are traitors), and people can fly over SpaceX's latest acquisition Area 51X if they buy the rights.

Project 2025 was not written by Trump even if he is the executor/scapegoat. Smart people exist and work for the politicians, shareholders and lobbyists that shape current US policy. And trial balloons don't need to be cleverly worked out, in the era of Trump you can just throw stuff at the wall, see what sticks, and pay private media to not make a story out of the rest. There's a good chance this will come to nothing, but why wouldn't a petty technocrat try to ingratiate himself to the new technofascist regime by offering a win-win.
