> I guess you could tax all collateralized loans above a certain collateral value but that can be gamed. So personally I prefer consumption taxes.

Interesting idea. We sort of already do this, we apply property taxes based on the value of the property as pegged at purchase (re-assessed over time). We could exempt loans on collateral already subject to property (or other value-based) taxes, but could then put a wealth tax on any other asset used as collateral for a loan at the collateral value agreed on by the lender.
