Lessig seems to think that people who have power will give it up willingly. Why, because "it's the right thing to do"? Ha, Lessig, tell us another funny one.
We're not going to get approval voting or any other method that satisifies the Condorcet criteria, because Duverger's Law, simply restated, ensures the power of the current political elite.
Lessig did some reasonable work with Creative Commons (even if CC0 is the only free license, CC is still successful). He should use those talents to try to educate people that the "Two Party" system is a cabal of political oligarchs who fleece the people by convincing them they have a choice when in reality there is only "fork over your money or something bad might happen".
