Again, Jeff Bezos does not "own" Amazon, he has 11% of shares -

He can't sell "his" company if he doesn't own a majority of the shares to make it "his" company.
Compare that to Zuckerberg who owns about 58% of shares (at least voting shares) and you have a dude who ACTUALY owns the company given his majority ownership of the stock.
You're acting like needing to sell a few hundred/thousand shares is asking them to go into poverty or lose control of something they never had control over to begin with.
That he'll have to sell off some shares? No, I don't. Because that's pretty regular/routine shit for anyone come tax season if they owe taxes and don't have the liquid cash to cover it. Will he still own most of his shares? Yes. Will he still be fabulously wealthy? Yes. Will it negatively impact him or his ability to invest in new ventures? No.
