There may be serious problems with electric cargo bike friendliness at the home end of dependency on an electric cargo bike: it's size and bulk, and charging requirements.

Its size limits its use to owners with the ability to store and charge it at ground level, presumably a garage or secured ground level storage area; stairs seem to be only for strongmen acrobats, elevators are a maybe in some locations but those same apartment houses probably do not permit indoor charging of ebikes; overnight parking on city street sounds iffy for security purposes as well as charging logistics.
