My AI art generator works right now, on my PC. If everyone stopped making art, the "normal" way, my AI art generator would still work.

This is a false equivalence to your example, because if farmers stopped farming, then it would not be possible to make burgers.

But, thats usually what happens when someone comes up with a pithy, one off meme response, like you just did, instead of actually responding to the substance of the argument. (I expect any future response from you, to instead not be engaging with the substance, and instead coming up with reasons why the silly analogy still works)
