High property taxes already exist in many places, why don’t people intentionally blight their properties and destroy their buildings simply to evade the property tax on a widespread scale?
In the US, it's because the current systems keep taxes so low already. There are few places where high property taxes are enough to cause the wealthy ire. Usually it's middle class people that complain about being taxed into unaffordability. They don't have the resources to drive tax valuations down.
Sure it happens sometimes, but it seems like a marginal exceptional case, rather than a rule. I have a very high property tax in my area and people seem mostly concerned with increasing their property values, not lowering them. There are other things they try to do to lower their property tax burden, but actively destroying their own property values is very low on the list.
