ELI5:Why is it legal to use adblock and listen to music for free on YouTube but illegal to download the music to your phone?

Youtube is a streaming service. A stream works in much the same way as a radio: A broadcast is made, and you tune in to listen/watch. If someone broadcasts illegally, it is not illegal to listen-- it is illegal to broadcast.

But when you download, you are taking illegal ownership of a song or film, and that is punishable.
