The only problem is that it’s still confiscateable. Like everything else a diversity of assets is still good. Real estate, crypto, gold/silver and other hard assets. Varying levels of liquidity and ability to be seized.
It’s also highly impairable. They can increase your property tax rate, your assessed value, and/or your rental income tax rate to such an extent that they decrease the value of the real estate in an instant. And this can come from the government at any and every level, be it local, state, or Federal.
