As someone who leans towards a general rule of government == inefficient but doesn’t necessarily like the logic of “billionaire individuals will allocate it better”, I really like your option C re-frame here.
Yes. I'm far less worried about government == inefficient (I've learned too much about AI and the genetic algorithm to have faith in human-based optimization strategies, and this is one reason I'm enthusiastic about population-based optimization along Basic Income lines) but possibly even more offended by the logic that specifically billionaires will allocate wealth better.
I feel like the very existence of billionaires demonstrates that they are a self-selecting pool of abusers and/or criminals running exploits that place their interests above the system they're in. Even the idea of 'the wealthy allocate money better' is ridiculous. Towards what, themselves? It's like saying cancer allocates body resources better, because cancer can get into a position where it conclusively 'wins'.
