> Homeowners already pay a wealth tax.

If you're talking about property taxes, then renters pay that as well through their rent (which passes through the landlord before getting to the city/county).

And is some (many?) cases higher rates than owners:

And even if the house represents negative wealth - same property taxes apply to a house regardless of whether the owner owns it outright with no mortgage (wealthy) or if they're paying 8% interest on an underwater mortgage (negative wealth). And, unlike VCs, property taxes are paid - often for decades - before one even sees if they'll even realize any wealth from the estimated value of their home that they pay tax on.
