People will just tear down the extra building rather than paying the tax.

This happened in Switzerland, where towns with more vacancies were assigned a higher number of refugees. In order to avoid this the towns demolished the empty buildings.

Well then I suppose we could write a better law than the one Switzerland created?

I don't think anyone is recommending we reimplement failed efforts, line for line.

I don't think this is an issue that can be solved by authoritarian thinking. If politicians do something people don't like, people will vote them out next time around.
