ELI5: Explain Like I'm 5

First-sale doctrine

The first-sale doctrine is like when you buy a toy from the store and then you can do whatever you want with it because it’s yours. You can play with it, give it to a friend, or sell it to someone else. It’s the same thing for books, movies, and music. When you buy them, they become yours and you can give them away, sell them, or even burn them (although I don’t recommend that!). The first-sale doctrine says that the person who buys something has the right to do whatever they want with it because they own it. This is a good thing because it lets people buy and sell things without worrying that they’re doing something wrong. It also helps keep prices lower because people can sell things they don’t want anymore and that helps competition. So, remember kids, the first-sale doctrine says that once you buy something, it’s yours and you can do whatever you want with it!
