While I agree with you, I think you over emphasize the technology and under emphasize the flawed contracts.
Eg, the copyright claim system seems fundamentally designed for abuse. You can't throw humans at it and expect it to work properly, it's working as designed now. You could change it, have humans handle the decision making or w/e - but if you are going to change it you could also "simply" write a better contract. Something not so flawed and easily abusable; of which there have been many ideas, discussions, etc.
