Or it allows people to waste excessive natural resources, rare earth minerals and electricity, when a little more effort is all that's needed to take them into that headwind.
Or it allows people to cycle into a headwind while avoiding one of the biggest benefits of cycling, maximal exercise. Leaving aside injury, infirmity or illness, the only reason people avoid strenuous exercise is laziness, and society at large pays the price for that.
It may seem innocent, even desirable (and compared to cars it most assuredly is) but nothing is completely beneficial and without consequence. I don't have an issue with legal ebike use, but I don't kid myself that its is completely without vice either. People ride them for many reasons, not all of them virtuous.
