I’m concerned that this EIP can be trivially defeated. You could easily transfer ownership to the marketplace, create and approve proxy contracts, or just list and sell wrapper tokens. Attempts to implement royalty payments on transfer on-chain are… difficult to say the least.
I’d encourage you to look into other alternative methods of generating continuing income. For example, Harberger taxes on NFTs have been a popular topic lately! (See Harberger Taxes NFT for an example.)
That said, nothing I’ve said here is a blocker for getting your EIP merged!
