land is also usually taxed. Squatting on it, at least the most desired/valuable kind, has a cost.
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.
