Do you have any stats to back that up? Sure, an ebike will be more expensive than an equivalent non electric version. But if you’re more likely to take it out over a car or paying for public transit, that’s much cheaper per mile of use.
For some anecdata, I bought an ebike 4-5years ago for about $1600 and put a little over 1,000 miles a year on it mainly in NYC. In total I’ve spent $600 on repairs and upgrades, with $300 being a new battery after 4 years. The rest was just replacing brakes and changing some of the stock items, mainly for aesthetic reasons. This bike replaced $40-60 cab rides to other boroughs and my unlimited metro card($130/mo). In less than a year it paid for itself and more, and I definitely would not have put as many miles on my regular bike.
