Well if you taxed people like Elon sufficiently maybe we would be able to use that to afford everyone in the country food, medical supplies and care, and more robust public transport. That quality of life increase to the public is certainly an example of an increase in wealth. You go from having no food to having it, having no healthcare to being covered, having less options for mobility to having more. These are valuable things that are now in greater abundance for you, that by definition is an increase in wealth.
No I am saying if you take 100% of Elon's money and redistribute it that would really only free up the things Elon consumes but can no longer afford. We can't turn money (which is just numbers in a computer) into doctors and food, it is just a lever for incentivizing production.
What would happen if you gave everyone in the country money to get medical care but didn't increase the number of hospitals and doctors we have?
