I have concerns about the level of power Elon Musk has, but I think what SpaceX has achieved over the last few years is really fucking cool and should be celebrated.

Isolated sure, cool shit. But done by Space X, a company that doesn't really think laws should apply to it and actively shits all over the environment because it's expedient. How they've acted in the past tells us how they'll act in the future, and it doesn't look good.
