I think your kid analogy is flawed because it ignores the fact that you couldn't reasonably use said "kid" to rapidly produce thousands of works in the same style and then go on to use them to flood the market and drown out the original authors presence.

Try this with a real "kid" and you'll run into all kids of real-world constraints whereas flooding the world with derivative drivel using LLMs is something that's actually possible.

So yeah, stop using weak analogies, it's not helpful or intelligent.
