I don't know. I honestly think the underlying agenda is simpler than that. Musk was already flirting with Europe's authoritarian-leaning parties before the whole DOGE fiasco. He played a key role in bringing non-establishment parties into the game, the kind of parties that may not have a lot of luck finding other means of funding themselves.
Truth be told, from a billionaire's perspective, having a friendly authoritarian ruler in power is much cheaper and easier to manage than bribing (I mean lobbying) a whole range of politicians with their own agendas. Ending democracy is... good business. I mean, until the "friendly" dictator turns on you, a lesson that the sociopathic economic elite keep forgetting.
