OK, so here's the thing from a politician's point of view:

If you do something fairly extreme for curtailment, like a tax on fuel that motorists really notice, the other party will get voted in and they'll undo it. Now you've got kicked out of office, with no environmental benefit to show for it.

And if you go further with something like a ban on pet dogs or ban on meat-eating? Same thing but faster and with more certainty.
