For people with a strong bias towards "pay as you go", it's not a sad future at all. The headache of managing bought content in terms of backups, syncing to various devices, changing formats, essentially making everyone a expert in storage management is one that could use some creative destruction.
I already got rid of my collection of music videos in favour of youtube playlists, movie collection in favour of a netflix subscription, document store for Google docs and would dearly love to get rid of my mp3 collection in favour of a streaming service. Spotify et al cant get here soon enough for me. Once that happens I wont be in perpetual fear of my laptop breaking down (just replace with another netbook) or losing my various cd/dvd/flash-drive backups.
If one day I'm not able to afford these services or a net connection, I have bigger issues to worry about than being able to enjoy the movies/music.
This stuff is not rare enough to make it worth me owning a copy (unlike in the 90s or before)
What a sad future that would be, an extension of moving your data in the cloud.
