For random “copyrighted” content like say my blog scrawlings, it would by default be under a CC attribution license unless I paid copyright tax on the content. Ie: default open not default closed.
Curious if any country does this?
It's an interesting point. I believe (chatGPT4 agrees) that taxes on IP occur via licensing deals, on transactions, and/or through registration fees. But not through anything resembling a RP wealth tax. There are probably some corner cases though.
Ownership of creative works you create yourself does not deprive anybody else of anything, so is less problematic.
Because land is real property. Unlike the made up BS that is intellectual property which is just like trying to own numbers.
