So who is going to buy the existing investor's wealth? Are they just going to buy each other's wealth?
Another example is McKenzie Scott selling billions in Amazon stock. There's no shortage of buyers for that.
Why would they buy?! You're saying it as if the market-wide sale of a share of every billionaire's stocks that year would just be absorbed by the market without any negative economic consequences (at best) or without a massive economic crash.

That wouldn't be the case if every "McKenzie Scott" is selling billions worth of stocks simultaneously. There would certainly be a shortage of buyers.
