I think that government intervention here is needed in order to coordinate people. We'll all be better off once ivp4 is dead and buried, but the incentive for each entity to do so is minimal. It could be some other powerful entity instead of government, for example tier 1 ISPs degrading ipv4 performance substantially or Google delisting websites that don't support ipv6 (and eventually delisting websites that do support ipv4).
