We already have Musk acting like his own personal country, making personal deals with world leaders that benefit only himself over other nations. Others are probably doing it, too, but we haven't heard about it.

Now these Sociopathic Oligarchs are heading to trillionaire status, and they WILL be founding their own Corporo-Nations, which will require private armies for security. Eventually, these Corporo-Nations will combine to form their own alliance, combine their armies, and start throwing their weight around militarily, as well as economically.

This is all just a matter of time, and then we're going to wonder as a planet, Why we didn't stop those guys back when we had a chance?

I have no doubt at all that ALL of them have violated many laws, in many sectors, to get as rich as they are. Investigate them deeply, prosecute them for their crimes, and confiscate their entire fortunes. If we don't do that, it is absolutely certain that we will come to regret it.
