E-bike motors are far from useless. They flatten hills (especially for heavy cargo bikes), help prevent you from showing up to work sweaty when commuting, make it easier to not pick the car on those days when you're feeling lazy, speed up utility cycling trips, etc.
I take my kids to school every day on a cargo e-bike. Having tried it with my 'acoustic' bike and a trailer back when they were smaller, I can state for absolute fact that if my bike didn't have a motor in it, they'd be getting driven in a car instead.
Also, just a friendly reminder: you're entitled to your opinion, but misinformation is considered uncivil and therefore a violation of Rule 1. You can say that you don't like e-bikes, or that you consider them "cheating" or whatever, but the notion that the motor is too small to make a difference is a false statement of fact.
