No, I just thought I'd point out that it is in fact illegal.

I think your moral justifications are simply that; justifications. Stealing isn't right, and if you don't want to support an artist, don't buy their work. That is, in my opinion, both the legal and moral way to be on the right side of artists.

I'm still confused. Approximately nobody thinks copyright infringement is legal, even people who spend all day doing nothing but pirating media. There's no reason to point it out. Secondly, "you aren't allowed to use that as justification" means something very different from simply pointing out that the activity is illegal, at least to me.
