You just moved the goal posts from "impossible" to "not economically feasible" - those aren't the same thing. I agree, economically, it's very difficult. We need governments to help with the cost, because it will be enormous. The cost of not doing it is even higher.

Also, the % of people who live in climates like yours is relatively small, so everyone who doesn't live in those places should not be using this as an excuse for inaction.
