If you’re dense enough to think saying you value something at $0 and then still enjoying it like the other people willing to support the IP, then you’re an asshole.
This isn’t even a coherent sentence. But I’m assuming you mean I’m an asshole for enjoying something without paying when other people do pay? Except if I enjoy something I do pay for it. Just because I don’t think people should own ideas doesn’t mean I don’t support creators when I enjoy something.
If you force that transaction by stealing their idea and efforts, you’re being a thief. What you use to justify your actions is up to you, but you’re a thief nonetheless.
And no, by law I am not a thief. A thief is someone who commits theft, and theft is “the felonious taking and removing of personal property with intent to deprive the rightful owner of it.” Copyright infringement does not deprive the owner of it, it is simply a copy. At least in the United States where I live copyrighted works are not considered stolen property. You can call me an asshole if you want but by definition I am no thief.
