This kind of thinking denies the humans in question any agency over their own lives. You’re essentially asking for a word government and a planned economy. Does it suck that more resources aren’t funneled into cancer research and other noble pursuits? Yes. But planned economies haven’t cured cancer, and are not likely to, despite denying their people the agency to live their lives as they choose.

I don’t think you have to go from here to planned economy straight away. There are capital gains taxes between the current level and 100% which might produce better outcomes.
