OK, why not high res scan all those Picassos then and burn the original paintings? Should be sufficient to have this _piece of art_ in the digital domain.
You assume that cassettes are all mass-produced artifacts. But that's not true. Many of them have a limited edition of perhaps 50 copies. But what I wanted to say was something completely different. People like to own art in a physical way. But to implicitly tell someone whether or not they should own something made of plastic is, in my opinion, crossing a line.
Digital media is a great chance to not collect more plastic stuff.
