How to Rent NFTs in Theory?

User guide for already open rent model
At present, most NFTs are minted through the ERC-721 protocol, and the 721 protocol itself does not test the scenario that the NFTs' owner and user can be two different people, that is to say, the right to use and ownership cannot be distinguished. This means that if the NFTs are rented out, the NFTs' holder will lose control of the NFTs. Although the borrower can provide an over-pledge, if the borrower does not return it, the NFTs' holder can only get the over-pledged currency, whichever he likes. NFTs will never be taken back. From another perspective, in the GameFi field, if the borrower is allowed to over-collateralize, the borrower can actually use the mortgaged funds to directly buy NFTs, and there is no need for rental, even if the original intention of the borrower to rent NFTs is to try the game. Therefore, from the perspective of both the lender and the renter, they hope to achieve the separation of NFTs' ownership and use rights. For the lender, they firmly control the NFTs property, and for the borrower, they can use a very low deposit threshold to rent the NFTs for use.
The separation of property rights is the basis for NFTs to be rented reasonably. There are currently some exploration schemes to realize the ownership and use rights of NFTs.
