I agree, I think they're an interim solution for not-very-bike-safe societies. (And bike-safe societies for people who are actually carrying cargo and have to use a big vehicle one way or another).
I've read that in the Netherlands, they aren't as common as you'd expect, because kids just ride their own bikes almost as soon as they're able to walk, because school, sport etc is nearby and on a safe separated bike path network. While younger babies are carried in those little seats that mount on the handlebars or racks of regular bikes.
I don't think ability to be carried up stairs easily is a good criteria for the practicality of any bike though, or it rules out many ebikes too. Just need secure parking at the ground level.
We're not all not arguing that though. On an ebike powered to 30km/hr, that's an 80 minute ride. If their small town supplies most of their needs and they go into the big city once a month, that's quite feasible... lots of people do a 90+ minute drive once a month for something or other. 1-2 hour rides aren't exhausting or requiring special fitness on an e-bike, and can be very pleasant (if they had nice routes).
Now if they mean they go 40km to take the kids to school every day, that's a different matter.
