Touché.

This will arouse the ire of the “copyright infringement isn’t theft” people - but we also have the government enforce shoplifting and larceny from retail businesses.

I believe the legal cost to recoup the loss of either IP revenue or physical property will be born by the victim though.

Right, that's one of the terms of the Berne Convention that I am referencing.

Taxing copyright ownership is effectively impossible.

Unless you want to figure out how to receive a tax bill for the comment you have written.

Just about any written or artistic artifact you create is subject to copyright protection. How do you begin to decide how a tweet should be taxed

I'm in the UK. Simply owning land does not incur taxes here, we don't have land value taxes. You pay capital gains tax on profits selling land. There are annual taxes on buildings such as council taxes on houses, specifically to pay for municipal services, but not generally on land.

If I make goods I'm not taxed for owning them, only if I earn income from the sale or use of those goods.

Real property is taxed, but often you do not pay capital gains on sold real property (this "often" of course varies by jurisdiction, so yes in lots of places you may pay some if the conditions are right), when selling intellectual property you often (same proviso as before, only inverted) pay capital gains.

IP is next to impossible to appraise, unlike land.

It’s pretty easy to ballpark what a lot of house or office building is worth based on comparables that sold recently. IP doesn’t sell that much and comparisons are harder.

Real property is sometimes taxed. Certain uses/users are partially exempt from taxation, and some uses/users are entirely exempt. It is not legal to rob these properties, nor should it be.

Council taxes could be considered propertie taxes, I guess, though I've always thought of them as paying for rubbish collection & etc.

However council taxes are paid by the residents of a property rather than the owner of a property. Granted these are often the same, but consider the case of a landlord with five properties the tenants would be paying those.

In the sense that Americans talk about property taxes as an annual thing I believe that distinction makes it a slightly different thing..

(And council tax is only a thing for property, if you buy a chunk of land with no houses upon it you pay nothing.)

They're not exactly proportional to the value of the property though are they? There's folks in London with multi-million pound mansions who pay the same or less in council tax than a family home in the suburbs.

Well, technically they're annual, but you're allowed to pay them in arrears over 10 or 12 months.
