The output of Claude is not eligible for copyright protection. I'm not sure how the analogy of bootlegging DVDs would work, given that.

I suppose you are violating the TOS by reselling a service, even if the output can't be claimed as belonging to anyone.

You can write anything in TOS, many parts of it is non-enforceable and depends a lot on the local laws.
