When you compare the places worldwide and in the US where governments are pushing and where governments deny change and intentionally do nothing, there is a stark difference in progress. There can be no doubt that current levels of government effort basically perfectly correlate with the amount of progress done. California's government is the only reason the United States has any competitiveness on electric cars, lithium batteries, solar panels, and without CA, the other 49 aren't in the same universe as China or Europe in this space.
Ultimately, I don't think there is any future for human civilization as we know it if climate policy is purely a grass roots, bottom up, consumer and market oriented change. I believe the government-minimum scenario is the billions die when breadbasket regions fail and mass famine hits scenario
