It lets you get loans based on 100% of your pre-gain money with zero taxes paid, which I think is too generous. You wouldn't do that if it was actually all your money. It mostly fits the idea of only taxing the "used" money, but not entirely, and I don't really favor that idea in the first place.
> It only takes a small rise in interest rates before it’s cheaper to pay the tax—assuming the tax isn’t outrageous.
15% tax is pretty big. And if we put capital gains back in line with income tax it would be double that.
> Unsecured are much riskier because of the way unsecured creditors are treated in bankruptcy, so they already have higher interest rates.
If the unsecured loans only go up to 90% of the post-gain asset value, that's not much riskier, is it?
> We also already have regulations governing how banks assess creditworthiness, and the percent of their capital they can lend unsecured based on risk. As well as the amount of unsecured loans they can make to signal individual. If necessary tweak those values.
Yeah okay we could stop unsecured loans from happening. That seems awkward though.
> Another easy way is to add a surcharge to large unsecured loans where the loan amount exceeds the taxpayer’s assets based on acquisition price by some large margin.
I don't like this one at all.
