15¢/kWh for industrial/commercial power is not the whole story. Say for example, the strip mall (auto mall etc) can pull 250kW's or 500kWh's at any one time in a month (turning on area)? That's going to require a nice new (big) transformer. That facility may pay a base amount easily in the 5 figure range, in addition to the paltry 15¢. .
His point is counter to your statement: @3PriusMike showed how the availability of convenient charging is not stopping EVs from being widespread.
My point is that the vast majority of current cars are parked at a home with a garage or carport. >90% in the western US, less in other locations; and that the number of homes with garages or carports is increasing. This means that having a place to charge isn't much of an impediment to overall EV adoption. For those that, by choice or necessity, live in apartments they will have to charge at work or a fast charger, mostly in the short term. However it isn't like there are zero EV chargers at apartments. Here is just one company that owns 250 apartments complexes of which 70 have chargers (as of a year+ ago, it seems) Charging Electric Vehicles at Apartment Communities | Essex I highlight this just because I happened to drive by one of their buildings during construction a few years ago and wondered if they installed chargers. Not only did they, they seem to be EV advocates...installing >200 in 2020. So sure, someone who lives in a 4 unit 50 year old apartment probably isn't getting an EV charger next year unless they swing a deal to pay for it. But bigger, newer complexes are being designed and built with EVs in mind. And these tenants are probably more likely to be early EV buyers as well. Mike
