Before there were cars, there were no laws (or traditions) regarding cars.
Until recently, there wasn't a possibility of LLM creating haikus.
When did this social contract you mention appeared?
And when they were invented, we applied our existing ones to them. It's not like running people over with a carriage was fine because cars didn't exist yet.

Yes, and? As if people couldn't have possibly had an opinion about that, because this specific type of dishonesty wasn't technically possible before? There was plenty possibility of plagiarism. Not just pretending something is a mind when it's not, but pretending it's from mind A when it was actually from mind B, and that was and is considered kind of a deadly sin by many.
But even then, now that is a possibility for an LLM to "create" an haiku, the reaction is overwhelmingly negative, so what's so hard to accept here?
