> The reason sneaking into a sports stadium is wrong is not because it deprives the stadium owner of the $0.01 marginal cost of an additional person being present. It's because it deprives them of the opportunity to sell a ticket for $100. The argument is that pirates wouldn't have bought the song, so it's not depriving the artist of any revenue. The pirate either doesn't have the song or they pirate it. Buying it is not one of their options. The stadium owner would never see the $100 because the person couldn't afford to purchase the ticket. So, it's not lost revenue to them. However, if someone sneaks in, now you're costing the owner money. That's why I'm saying the in-person analogy doesn't fit.
