I am in agreement with a lot you say other than a couple of points.
An e-bike does not change the very essence of what a bike is, imo. It just gives an additional option. The essence is still two (or three) wheels powered by the rider and that will not change.
That maybe in the EU, but here in N America people have pushed the envelope with the E-Bike laws and 750 watt with a throttle is NOT the same as 350 watts and no throttle... 
I don't begrudge an e-bike to anyone who wants, not just needs, one.
Perhaps we have different experience of e-bikes here in the UK, as there does not seem to be much of a problem with souped-up e-bikes.
Well most people seem to be buying E-Bikes here for a faster ride, using a throttle, not just for some assistance while pedaling... 
Myers-briggs takes me back 25 years when I used to use the questionnaires as an aid to recruitment and team-building. My issue is that we are not necessarily talking about the truth here, we are talking about opinions, which can differ. I do not want to call an apple an orange, just a fruit. I will continue to ride bikes, but possibly one day, in the hopefully distant future, of the e variety.
I actually hired an e-mtb last year for a half day in Lake Garda, Italy, and loved it, but I do not have one on my wish list.
