All other things being equal, we do seem to be getting better at decentralized governance of a sort. And part of that process seems to be that someone has to get enraged and throw a "radical proposal" out there to shake other people out of the comfort zones and start looking at issues.
As a metaphor, someone yelling "Let's overthrow the government!" isn't necessarily a reason to actually do that, but a good reason to wake up and start talking about what's wrong with the government.
Bright Blessings!
Radical proposals do tend to frame the debate! Very good point.
