Probably get a license though. A real emergency is when you're most likely to make mistakes behind the wheel and you're going to be in a lot of trouble if you get in an unlicensed accident.
This might depend on location. For me, maintaining a license works out to a few USD/yr so you might as well do it if only for emergencies, to avoid a citation in an emergency (though I'll admit it's far-fetched for that to occur). In a place where licensing is expensive, I'd agree with your take.
Or learn to drive, at least. I don't think lack of a licence would stop you driving in a real emergency.
