It appears LordBucket's argument is against any system ensuring that, not just against the current system. I think alot of people here are agreeing that the current system is either doing a poor job, or is just overkill.
LordBucket isn't against ANY system insuring that, just against copyright, near as i can tell. And has been discussed several times, there are multiple other systems in use right now.
Personally, I am against any but an extremely limited kind of copyright. I think we do not, as a society, need to do actively encourage creation any longer in the artistic fields - the sheer preponderance of opportunity has resulted in an incredibly explosion of creation, and I would wager a guess that the amount of art created for free or from patronage systems today vastly overshadows the amount that was created thanks to the encouragement of copyright 200 years ago, per capita. And it's become obvious that copyright laws, even in the first several years, actively
limit many types of creation.
I would support laws against plagiarism - but that's not copyright. That's attribution. I think there's still a strong benefit to such laws for promoting creation without also limiting it. But beyond that? I would be hard pressed to support the inherent monopolies created. I don't think copyright currently serves the purpose originally intended, and if it did so that would be an improvement... but I also don't think that the purpose originally intended is actually a purpose we need to actively pursue any longer.
Would this lead to the crash of the entertainment industry? Probably. But since it's an industry that has shown a willingness to pirate mercilessly from independents, pervert the political system, and use heavy handed methods of enforcement to insure a large enough pool of money for the executives (and not the artists, usually) to roll around - I'm perfectly fine with that. Let it die.
We'll adapt, people will spend their time doing other things, either looking at works freely distributed by hobbyists or by media created through a patronage system, or boosting other industries that provide entertainment without having to exert monopolies, and the world will be none the worse for it.
That's my opinion anyway.
