> Examples include Elon Musk and Peter Thiel, so-called libertarians with entire business that consist of "use your friends in government to get juicy government contracts and grow rich off that sweet, sweet taxpayer money" (SpaceX, Palantir)

Not true regarding SpaceX, they were just cheaper and better than the competitors. They had to sue the government to even be able to compete against Boeing/Lockheed for military contracts. Who had more friends in the government in the 2010s, SpaceX or Boeing/Lockheed? In 2014, NASA awarded two contracts to develop spacecrafts for transporting astronauts to the ISS (at the time, American astronauts flew to the ISS only on Russian Soyuz). SpaceX received $2.6B (for Dragon), Boeing received $4.2B (for Starliner). Since that time, SpaceX has made 11 operational flights with astronauts to the ISS, while Boeing has made 0 (they're still working on it). It's not friends in the government, it's delivering services faster and for a lower price.
