You mention legal speed of ebikes but use mph- what country are you in? In the USA, it's 28mph. Also, my ebike does fine for parcels/shopping, it has a rack. If it's hot I use more vehicle assist and less human power. I see cargo bikes for larger loads like children. Ebikes may not be for everyone, but they're much better than you portray.
