Condo fees go to a small body controlled by people who pay the tax. Property taxes go to a very much larger body which includes all sorts of people who, for whatever reason, don't necessarily pay the tax directly.

That inclusivity on the basis of legal status, citizenship rather than asset ownership/wealth, is the difference between civil government and a private club requiring buy-in. The requirement to own property in order to participate in government was abandoned long ago, with good cause. That system was horrible.
