I would venture a guess that "property tax" doesn't quite feel the same as a wealth tax to most people, because most people don't have a paid-off house, so it's just one more component of their mortgage (and paid through an escrow account rather than directly). If you're paying a large aggregated bill anyway, it feels like just one more tax associated with money changing hands.
If your house is fully paid off, such that your only remaining costs on it are property taxes and insurance, then you're already far more well-off than the majority of people.
Also, financing schools and other local services via property taxes is a bad idea; doing so perpetuates inequality by giving more funding to services in more expensive neighborhoods.

I mean, who cares? This is a tax on people with eight figure fortunes we're talking about. The only issue at hand was can the unwashed masses grok the basic concept here. The answer is of course they can. Sometimes you pay tax on value you earn, sometimes on value you give away, and sometimes on value you have. We all do it all the time on all three counts.
I don't care all that much about the taxes of people who have tens of millions, and I'm all for finding ways to fund better safety nets.
I do care that such taxes have a tendency to spread to lower tax brackets, once they're perceived as acceptable at all. I don't want to see wealth taxes being assessed on people in the "finally paid off the house" bracket, or the "successfully saved for retirement" bracket. And as long as those brackets are above the median wealth, there's a serious danger of that happening. It's much easier to argue against wealth taxes before they exist at all, and much harder to continuously keep them from affecting more people.
(Example: if wealth taxes become acceptable, I would not be at all surprised if people in areas where houses still cost 5 figures support wealth taxes at a level that affects people just like them who happen to live in areas where houses cost more. Arbitrary wealth taxes are not a power I trust politicians with, no matter how much they promise not to abuse them now.)
I also care that such taxes require much more invasive information-gathering (of much fuzzier information) to assess. (The value of property that isn't directly denominated in currency and isn't in the process of being bought or sold for currency is quite fuzzy.) Other parts of this thread already cover various aspects of that issue, though.

Taxes on "value you have" are quite rare; taxes on homes/land are just about the only common example, and those are already controversial for a variety of reasons.
If your house is fully paid off, such that your only remaining costs on it are property taxes and insurance, then you're already far more well-off than the majority of people.
