I think that the idea of trying to make driving more unpleasant (it's already deeply unpleasant at rush hour) both distracts from what should be the goal (making cycling better) and creates un-need antagonism - there is already plenty of that.
With regards to the mother of three situation- a car can be purchased for less than a Kristiana type cargo bike, a car can also be stored on the street with a reasonable assumption that it will still be there the next morning.
Finally, whilst fine for somewhere pancake flat, if you issued a "normal" mother of three with a cargo bike to transport her kids with in (for example) Forest Hill, then you are going to see a family in a taxi every morning.
