Of course, this won't be popular on the HN crowd, but I'll say it anyway: What we need is securities tax. Absolutely any conversion, collateral, or divestiture of securities need to be taxed at the rate of those securities at that time. A lot of plutocrats are playing the system by just basing their loans and the collaterals thereof, and their payments for things, on stocks and securities because they are "unrealized gains". If securities are enough of a bearer instrument to give loaners confidence for otherwise no-collateral loans, they're enough of a realized gain to be taxed when you use them for a purchase - or alongside one.
