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.

No they simply don't work either.
