Some altruistically-motivated projects would be valid investments for a Checkbook IRA. I guess if you wanted to donate 401k/IRA earnings to charity you’d still have to pay the 10% penalty (though not the tax if the donation was deductible) but that seems the same whether it’s pretax or a heavily-appreciated Roth.
