The main implementation issue with a wealth tax is that it doesn’t at all interact with the capital gains tax. It’s easy to fix the implementation issue by integrating the wealth tax into the capital gains tax (call it unrealized capital gains tax for starters), make the tax refundable when an asset loses value, and netting it against the actual capital gains tax.
With this framing, the wealth tax isn’t a new tax; it is only prepaying the capital gains tax instead of allowing it to be deferred forever.
Unrealised capital gains tax requires some way to assess the value of assets. This is a lot harder than it sounds.
It already exists in the form of property taxes, which are quite unpopular.
