I have been riding electric bikes for about 6 years now. I agree with most of what you say. I would add that these much too heavy bikes need at least 50 watts of assist to get them even with a cheap road bike for pedalling effort. That corresponds to the lowest level of assist for the three e-bikes I've had. I don't hesitate to add assist for uphill, upwind and soft ground travel, of which I encounter plenty. Even so, I can travel 30 miles on my current Rad without going below 3 of 5 bars. That's about half charge. I have zero range anxiety and my butt gives out way before my legs and battery.
I like to travel trails away from home on occasion , which means putting them in a vehicle. If the bike doesn't fold that means a carrier, which is a pain in the neck. Not that putting a 75 pound folded bike in a cargo area or trunk is any fun.
