If I had a hilly or longer commute to work, I would definitely consider buying an e-bike so I wouldn't arrive all sweaty (we had such a hot summer here in Utah). And also if I at some point develop physical limitations.
I think the resistance to e-bikes in the US is in part because here many folks still consider cycling purely an athletic activity (and feel the electric assist is "cheating"). In Europe, cycling is considered by most a mode of transportation and travel, or a way to enjoy nature and go sightseeing, and not primarily an athletic endeavor. The e-bikes are one way to make it more convenient/enjoyable.
