Elon Musk is mostly a bad person. I do not want mostly bad people to succeed. Why is that hard to understand? You either do no think he is a bad person, or ignore the fact he is.
I'm capable of understanding people are multidimensional and capable of both good and bad things. it's possible think someone is a bad person while understanding that not literally everything they do is evil. this project being successful will improve the lives of thousands of others would you rather the project fail and have things stay the same?
One of the killer features of the modern democracy/market system combo is that it can channel quite a lot of bad people's efforts towards neutral or good outcomes.
A scenario where Musk builds an interplanetary space company is infinitely better than a scenario where Musk is a warlord conquering some unlucky province of a decrepit empire with sword and fire.
Giving such people an option to succeed economically is probably the safest way how to deal with them. SpaceX > Attila, Amazon > vikings.
