But trademarks have some customer-friendly properties: if I buy a soda with Coke's trademark design on it, I can be reasonably sure I'm buying an actual Coke product. OTOH, we also have the IOC suing people for using "Olympic" in the name of non-related businesses (eg https://www.techdirt.com/articles/20150221/14095930099/olymp...), which should be a "too bad so sad" ruling for the defendant against anyone who names their organization after a physical location.
As an aside, I strongly believe that entities should have to pay taxes on their intellectual properties. It's at least imaginable that you could defend your real estate without the government's assistance, even if that means hiring armed people to enforce the borders you're claiming. It's impossible to enforce IP without the government's assistance, and I think it's utterly unreasonable to expect that government to lift a finger to help protect it without paying taxes on it. I ran this by Cory Doctorow and he patiently explained why this isn't possible, but I still contend that even if it can't be, it ought to be.
