I think the major problem a lot of people have with Elon's behaviour is not that he is behaving in an "entrepreneurial" way, but that he appears to be in the middle of a hypomanic episode and has nobody around him who has the ability or balls to tell him he's acting irrationally. And I say this as someone who is bipolar and has them on a regular basis. Most people (who manage their mental health conditions responsibly), have a group of people they trust to rein them in when they start going batshit. This usually involves things like taking away their bank cards so they don't spend all their money, dissuading them from making any major, life altering decisions, noting when you're lying to yourself and others, and attempting to point out that possibly behaving like a self aggrandising megalomaniac is not particularly healthy.

It's quite clear that Musk doesn't have anyone around who is willing or able to do that. Most of us when we go hypo will end up blasting through our savings, screwing around (literally) and generally pissing off all around us by behaving in a self centred and irrational way, but ultimately the damage we do is limited mostly to ourselves. Elon on the other hand has spent billions on a company, apparently on a whim, probably during another episode, that he later regretted and tried to get out of, again presumably when he came down, and now appears to be taking a series of increasingly irrational and destructive decisions that are affecting the lives of many. To be honest, I think it's kind of sad to watch.
