I understand you have a passionately held opinion about these matters, and it's unlikely I or anyone is likely to change your mind about much of it. But, as it's often said, you don't understand your own position thoroughly until you understand the other position thoroughly, so for the sake of you or anyone else who wants to be on solid ground, I'll put some responses.
To declare my hand somewhat, when I said I have no dog in the fight, that refers to Musk; I don't find him a particularly admirable person, or someone likely to lead bringing about the changes I want to see in the world. What I bring to this is at least a couple of decades deeply exploring the question of how every/any person can live with maximum liberty and agency, and achieve an objectively satisfying life, no matter the circumstances of their birth or other issues over which they had no control. Musk doesn't have a huge amount to offer on that topic, so I'm not here to support or adulate him, but I do care about words like "authoritarianism" being used with a reasonable level of accuracy, and I always hate seeing people being portrayed negatively on largely false grounds.

I'll note that your previous response contains a lot of just-so argumentation ("He likes good little workers and no back talk. He likes the authority"), and ad-hominem attacks/character insinuations ("It's always fascinating to see people being unable to believe that Musk is what he is"). You need to cut out these swipes if you want to be seen as an objective, good-faith debater.

To respond to your main arguments in the last comment:

- On Russia/Ukraine and China/Taiwan: He just seems to be focused on ending these conflicts with minimal bloodshed and destruction. He didn't argue for Ukraine to just submit; he said there should be an externally supervised referendum so the people in the contested regions can self-determine which country they're in and that everyone can peacefully accept the outcome. That's as anti-authoritarian as you can get. In both cases of Russia/Ukraine and China/Taiwan, he sees that the worst case scenario is utterly catastrophic (all-out global nuclear exchanges), and wants to find ways to resolve these disputes before it gets anywhere near that. As divorce negotiators will tell you, when everyone is playing an all-or-nothing battle, everyone loses, whereas if you can find a way for everyone to get 75% of what they want, a peaceful result is much more likely. It doesn't follow that his desire for peace is authoritarian; generally it's authoritarians who like endless wars. He's advocating for the most effective way to end/prevent war. You can disagree with his position, but authoritarianism is not the issue here.

- "Sure there is. He likes good little workers and no back talk. He likes the authority": You've presented no evidence for this, it's a just-so story, though a familiar one; plenty of people will similarly assert that he just wants to fill his companies with sycophants. The thing is, sycophants and "good little workers" don't get reusable rockets working reliably, nor newly developed automotive technology. The evidence I can see is that he wants highly skilled people who know their field extremely well and will just get shit done, not waste their colleagues' time and energy with endless petty drama. When people spend a lot of time stirring up drama, it's generally a pretty good sign that they're not so good at their work. So again, it's not about authoritarianism, it's about getting good work done without drama.

- On COVID lockdowns; you can disagree with his position, accuse him of playing the victim, fine, whatever. It just doesn't have much to do with authoritarianism. Clearly, the governments/bodies mandating lockdowns and vaccinations were authoritarian. You can say it was justified authoritarianism, sure. I've been fairly comfortable with the lockdowns and measures imposed where I live in Australia, which many have described as being very authoritarian. But you can't say the people arguing against lockdowns were authoritarian. Any criticism for opposing lockdowns has to use words other than "authoritarian".

That's probably enough of a reply from me; the earlier reply from someone else covered the rest.

As I said I don't expect to persuade you but if you must respond, please try to do so without ad-hom and just-so story.
