As a libertarian, I don't trust these billionaires a single bit to do it.
They are not libertarians, they don't care about the free market, small local business, regulatory and certification companies, or what else. They are very happy to lobby the government to enforce any anticompetitive practices that will benefit them in the long run. They probably just want a new way to evade taxes, they don't give two fucks about libertarianism.
Sadly, tech bros won't see through it and will hype anything these clowns do.
