While I like that mp3s made you think about distribution and delivery, let’s be clear that that’s a false equivalence: streaming media doesn’t take up any space after you’ve used it, other than the master copy/copies. You can’t say that about a shovel, or a camera, or a car. You can’t really say it about food, either, though we tend to not think about where food goes after we’re done with it.
The cost of maintaining a shared pool of shovels and cameras and cars is far above zero — and far above the cost of maintaining an archive of streaming media.
It’s not quite as simple as it might look.
Self-driving vehicles don’t get us there by themselves. Who’s going to load, or more importantly, unload them?
