Right now I dont think there is a programmatic way to do that with star certificates. I guess I dont see what your point is - are you just trying to link two things that seem frivolous to you?
You buy "something". That "something" doesn't represent any legal right for you. If you buy a NFT of an image, you won't be the copyright owner of that image. You can't stop other people from using it either. Maybe there are some exceptions, but generally you just don't get anything legally. Similarly, buying a star doesn't give you legal right on that star.
Why does doing this programatically make it different? Plus, buying a star is not inherently non-programmable. You can launch a star registry with an API. You can laucnh an NFT for stars. What makes buying a star stupid is that it doesn't represent any legal right, not that it's doesn't scale.
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.
In my hypothetical game I can enforce that relationship. Lets say the game is pokemon except with scorpions, and each scorpemon is represented as an NFT. Your wallet contents then determine what scorpemon you can play with.
Does that make sense?
