I have to pay property tax forever for a house I supposedly own. If I dont pay that, the government sues and takes my house. Basically I never actually own my house.
(Of course, we have "Evil Communist China" where there is no property tax, and people own their homes and can live there. Id argue they're more free than we are.)
But copyrights and patents and trademarks? There's no tax on those "properties". And gee, companies are the ones to likely own these properties, not individuals.
What? You pay property tax because local services schools, streets, police and fire fighters need to be funded. Having a property in the area is a pretty great proxy for using some of these services, hence the property tax.
