It gets you out of the reach of the suffocating regulatory states here on Earth.
Some of those states could project power in orbit if they wanted to. I'm not normally a hawk but I'll make an exception in this case.
If it's something that could even realistically be done, which again I don't actually concede based on what I said before, then maybe it would have slightly less regulation.
Or, and hear me out, Elon is just a drug addict who makes shit up based on his 12-year-old-boy fantasies because it sounds neat and investors just eat it up.
Are you forgetting that you need to launch from one of those "suffocating regulatory states"?
