Too many straw men here
The comparison was between bikes and e-bikes
There’s no comparison as an e-bike is exponentially worse for the environment than a normal bicycle.
No, the comparison you gave was between walking and cycling - not ebiking.
Exponential is an equation that in this context perhaps suggests the more you use, the worse it gets (unless you are using the word in a hyperbolic manner). Actually, it that's generally not true of bikes or ebikes:

The worst bike or ebike is probably the one that never gets ridden. May I suggest you post some stats to back up your gut feel?
