I'll try to keep this a short as possible.
If you stop the music producers (who the RIAA represent) from protecting their business interests, then the business will no longer be viable.
If there is no copyright protection everyone will just share everything. Not just by things like K++, but by direct links to web pages, ftp sites etc. These are much faster and more reliable.
The music industry business model will collapse. If that is what you want that's great. But rest assured it is not what the bulk of the population wants. You may all like to support the local artist and buy from independent labels (the majority of whom are probably members of RIAA), but the bottom line is that most people don't. They buy popular music, from music stores, take it home and listen to it on their nice wee CD player.
The bottom line is, no matter how many sabres you rattle or drums you beat you cannot win this. You have neither the popular support or the political lobby. So why not just download your music, have fun and stop wasting valuable time tilting at windmills.
