Buying used movies at a garage sale fuels the retail market? If that were the case then why can’t you buy used movies at any retail store? Another falsehood.

I’ve spent thousands on hardware and software for my media server, so it seems that piracy does fuel the retail market in ways that buying second hand doesn’t. Perhaps you’re right and they’re not the same. I think piracy generates more revenue than buying second hand, elevating it well above buying used copies, which is now the most harmful way to consume media.
