Think of it as going to a fancy restaurant. When you eat a fancy steak, it lasts a few minutes, maybe a few hours if you consider the whole experience, but at the end it goes in the toilet. But you had some enjoyment (well, unless you're vegan). You'd also get enjoyment from a much cheaper burger, too, but sometimes it's fun to do something different, even if the money is lost and you're left with nothing.

It works like that, except you usually still have something for a long time, even though it's digital.
