From what I read, Musk doesn't want your money for SpaceX/Starlink precisely because he doesn't want the funds of the company to be chained to a public perception war that distracts him from running the company, like happened with Tesla during the doubtful years when half of the market was betting against him. Why take public funding when you can reap all the revenue directly?
Being “public” has issue yes. That doesn’t mean we need maternalistic governmental policy to “”protect”” people.
It sounds like you're upset that you're not considered an accredited investor - but even if you were, it's not like SpaceX would just give you some shares if you gave them $10M.
