I get what you're saying, and this is what I thought until I got my road e-bike; I have a Trek Domane+. Looks like a road bike, feels like a road bike, tastes like a road bike, rides like a road bike. I'm not 100% sold on the accuracy of the power meter, I like the power meters on my other road bikes much better, but I could not believe how versatile it was. I used to think it was just for screwing around, people that don't REALLY ride, that kind of thing
I can do just about any road bike workout that I want on my Domane+. At the end of the day, you still control how much power you are using, it's just that the bike can provide some assistance if you want.
The thing about the road e-bike is that it gets me out on the road on days I would not ride on my other road bikes; more windy than I want to ride in, maybe the legs just aren't feeling it that day, or you're just feeling lazy. If the wind is blowing more than like 13-15mph, I'm just not riding one of my road bikes, but I'll get on the road on the e-bike and still get in 20 miles.
I guess in short, as long as I'm putting out 200W, or 225W, it really doesn't matter if the bike is offering me a little bit more. It just means I'm going faster than I would without it and for my riding, speed is honestly the last thing I'm worried about. It's not even on the first page of my bike computer; I only look at my cadence, my 3-second power, my average power for the ride, and sometimes grade and elevation.
1272 ft in 24 miles isn't bad at all. I didn't think anyone could get any kind of elevation gain around that part of the country. I can't go 7 miles from my house without gaining 700+ feet.
