I think the emotional attachement that people have with the physical media is valid.
However, back in those days there never was a choice. If you wanted to read a book, you needed a printed book. If you wanted listen to music, you needed a performer or a record. If you wanted to see a movie, you needed to go to the cinema. The sources of availability were very limited and controlled.
Gradually the creators started using digital technology to store their works. Later on the people were giving almost the same kind of digital technology to store their works on. Seems the digital technology doesn't really care who the creator is, because nowadays everybody can store everybody's work, no matter if you are the creator or the consumer. The sources are endless and there is almost no control.
With the gradual upcoming of the PDF, the MP3 and public available technology, all people now have a choiche.
The people no longer need books, records and cinema's. They can get it all (digitally) from other people, and thus other, endless, sources.
On top of that, the people have been given the methods to transform all kinds digital data into physical information by themselves!
This gives benefits. Imagine if the libary of Alexandria were to have backups all over the world. Everybody could have all that valuable information!
This gives drawbacks: The sources are endless and not controlled. There is no knowledge if the information was tampered. Everybody has the same information and thus it has no real value.
If you give them fire, don't expect never to get burnt by them.
