But if this is already true by default, then we're back to square one where the important financial decision was already made. Again, if it was already decided by default that there is no sale to be made, then whatever the end user does after that is irrelevant.

I've seen lots of people on this site that pay for YouTube. I've met real people that have subscriptions to porn sites. They fork out money for stuff that's pretty much always already freely available, for basically no reason except maybe convenience or slightly better service. People spend money all the time, for stuff they want and care about. If they didn't want or care about it, they wouldn't buy it or pirate it.
