How stupid of you for assuming they'd have to keep it, rather than slowly selling it off, indeed exactly like Mackenzie Bezos might do. You could easily mandate this.
Not to mention that the Norwegian Pension Funds holds $2 trillion in assets. UAE and KSA have ones over $1 trillion each.
And that's ignoring that currently an even smaller group of people owns everything, who don't even represent the public on paper. Quite stupid to assume that this is a better idea.
