Sure, if you use a nonsense example you get nonsense results. Not really blaming you for that, I have no idea why people acted like an NFT with a url payload represented ownership given that it didnt interact with any of our systems of ownership.

The hypothetical under examination here is if I built a system that used NFT ownership as ownership of some in game thing - it represents a promise to value a given token, which is wholly different from the star thing (they dont value that certificate in a meaningful way). If your first instinct is to launch into a tirade about how dumb that is then great - total agreement. But, you could build it and it would work, and it would be meaningfully different from star ownership certificates.
