This sort of reminds me how land (not property) tends to be under taxed. Land requires administration and military protection which is an ongoing fee but there are a lot of people who think it should be free. This then requires cross subsidization by income tax which in turn means the GDP must never go down as that would cut into income taxes that pay for land related services which are provided for free. Here the NFT is kind of like land in that it requires both administration (OpenSea) and protection (Proof of stake). In principle the owner of an NFT would have to pay an insignificant "rental" fee to keep his NFT alive/hosted.
