Oh, I assumed you were talking about sales taxes, which is the most obvious case of a DAO-like organization taking money on every sale, as a percentage of the selling price.
Income taxes and capital gains taxes are on your profit, not on the sale itself, so they're less analogous. If you as a taxable entity don't net make any money, you don't owe any income taxes (more or less); if you as a taxable entity don't make any profit on an asset you bought some time ago, you don't owe any capital gains taxes (more or less). So both of those are much more reasonable than a royalty on every sale - they don't follow the asset around forever, and you only have to pay a percentage of the money you made if you're in fact making money. It seems like, if I buy an NFT at $10000 and then sell it a month later for $9000, some of that $9000 goes to the creator of the NFT and not to me.

Yes that's correct. That makes it very appealing for creators like artists. I can see how that might be off putting for you though, but I think over time this will become "priced in". Also, only ver few creators will have an active aftermarket for their work. Most will not have a single aftermarket sale.
