But you -did- essentially say it was okay. Your mode of thought is exactly what larger companies use to justify their actions when stealing from other artists. Not to mention the fact that it can ruin the integrity of the IP or reputation of the artist, depending on where it is sold, what it is sold on, or what it is sold with.

So, just because you're okay with someone selling your own art that wasn't a commission or isn't being sold as a print, doesn't mean every artist should want to do the same.
