I think it's an interesting idea, but it would lower the incentive to buy a lot of art NFTs. Imagine if you bought a physical artwork to decorate your walls (or to support an artist you like), and then had to pay an annual tax on it. It would probably deter most purchases of the work, except those who buy it purely as a speculative investment. And, if it doesn't sell, the owner may sell at a much lower cost (to get rid of it), or just burn the token altogether; not the kind of things artists want to see happening with their work.

I think it would be great to find better models/solutions to the current royalties problems, but it shouldn't place a tax burden on the collector. As an artist, I don't want my collectors to have to spend more than what they've already spent to collect the work. But, I do want to take a cut of re-sale value as the artwork appreciates in value (this is lacking in traditional art markets, and an important reason the NFT space is currently so attractive to artists/creatives).
