I can think of a better analogy than littering for pirating an item at more than 1 place. When you litter, you add to the trash. If everyone littered, it would be awful. But if everyone pirated the same content on a different site/platform/protocol, it would still be 1 pirated item.
The better, IMO, analogy, is if you have an ad glued somewhere, say at a bus stop. Another person comes with their ad and wants to glue it. They glue it over the previous ad. The amount of ads visible remains the same. There's a negligible disadvantage for the city - they have to haul away twice as many paper. But most importantly, the amount of visual clutter hasn't been increased if the second ad is glued over the first one.
That analogy works if you're against piracy and ads on public places, of course.
