I think the Cynical Musician went to the max on this when he said " unauthorized copying is to theft as ethnic cleansing is to genocide".
The metaphors and descriptions that arose i a non-digital age don't fully track to what is happening in the digital age, but so what-it's the underlying conduct that really counts.
The law of copyright was was originally passed so as to enable the creators of works of art and science the ability to recoup and live on the fruits of their creativity. The need for that remains today, and so copyright law needs to be not abolished, but updated. Instead of a total ban on copying, there needs to be reasonable restrictions on the number oif copies that can be made and that can be done with those copies. If that sounds suspiciously like Digital Rights Management, well, there it is-the elephant in the room .
Now you may say that current DRM schemes are a steaming pile of horses#$$t and I may even largely agree with you but copyright law and DRM are probably going to be inevitable -as long as we want creators to keep on creating.
