Lots of assumptions and unknowns.

Implement a carbon tax and watch the market reconfigure itself.

Also: let's re-legalize corner stores!

Just because a carbon tax re-organizes the market doesn't mean that the organization that it "chooses" is good.

It means the reorganization will optimize for less carbon usage though, which I happen to think is pretty good.

Electric vehicles might complicate things some (they still present some other negative externalities despite using less carbon); perhaps at that time we can look at other incentives or taxes.
