The problem is that we no longer have the time to let market forces work that slowly. Things like home heaters, stoves, vehicle engines, etc. have service lifespans measured in decades so we need everyone buying electric now. Things like EVs or heat pumps often have higher upfront cost so we need to stop having the situation where people feel like they have to pay more to do the right thing because the fossil fuel prices are subsidized so low that many people don’t feel much pressure to change.
