Speaking totally anecdotally here, but one of the big benefits I see in the DMCA system is the ability for individuals to have an easy, free way to deal with any copyright infringement. I have a few friends who create art as a hobby, and they have been able to deal with people or companies who illegally re-upload their art for monetary benefit (such as merchandise).

Obviously the system isn't perfect (and there are absolutely better solutions), but it does have its merits.
