> And that's not even to mention that the assets in a Roth IRA are essentially worthless to him - he's not old enough to make withdrawals or take distributions tax-free and you can't borrow against a Roth IRA I don't think that's remotely true. For a normal person with tens of thousands or even a few hundred thousand in an IRA that money is basically useless. But for someone with billions in an IRA? He can almost certainly start a public company and use a maze of shell companies to let him do whatever he wants with the money.
