> People would argue that it's up to the seller whether they want to make their creations available. If I don't want to sell you something, then I'd entertain the argument that downloading it anyway is in some sense immoral or unethical.

I would say another key distinction is between "don't want to sell/can't sell" vs "don't want you to buy". In the former it may be because the owner does not want to go through the trouble of selling it or is no longer around to sell it. I know some people have given up because the effort to deal with "trolls" (particularly DMCA and fakes) has either turned their passion into a nightmare or it's not really their passion anymore and they don't want to deal with it.
