I bought a used Volt about the same age and miles for the same price ($10k-$15k). Its starting MSRP was the same as a Model 3 is now. So I have almost all the advantages of an electric car. Model 3s will get there, too, eventually (the fact that used prices are still super high tells you that people love the car... also, they've only had the cheaper trims in large numbers for the last year or so).

Your argument can be applied to any new car. Buying used EVs will be the better deal, just like buying a used ICE is a better deal than a new one. Certainly the case for me. I've spent nothing on maintenance (except tires and wiper blades) and very little on fuel (electricity is equivalent to $1/gallon gasoline).
