Why would game developers ever implement a system that lets you circumvent the rules?

What? They still have to write code to interpret the NFT in their game. They still need specific integrations for every single token they need to support, and they also control what that token is. If they choose to interpret your really expensive sword as a common one, well, tough luck.

This is just centralisation -- entirely.
