If you look into the history of Tesla and SpaceX you'll realize Musk would have gone broke years ago without government money.
I've never met a libertarian who didn't decry government subsidies as socialism, encouraging freeloaders, and feeding the nanny State. But take away their own subsidies and they scream bloody murder like a baby pulled from its mother's teat.
