What's unrealistic about this math? Just because the math involves new parameters (EG amortized cost of charging infrastructure & cost of electricity) doesn't mean it's fabricated. Even level 1 charging (as you call it "overnight slow charging") gives you ~5 miles per hour and only requires a cheap charger of ~200 bucks. Charge it from 8PM to 6AM and you get 50 miles of range. If you have a <50 mile commute, you can charge from 8PM to 6AM, and your work commute is taken care of. Charge a little longer on weekends and you can budget further. This situation might not work for everyone! Street parking of course makes this nearly impossible. But A LOT of Americans have a <50 mile commute, and a garage with an outlet. For these people, they're saving money every day, and never have to use a gas station ever again. In this situation you'll pay off that initial $200 in ~8 months. But even disregarding financial savings, many may simply prefer the tradeoff of not having to go to gas stations in exchange for plugging in when they return home. Then, if you need to go on a >200 mile trip, you have to use a public charger, and the math is less favorable as those will cost more and you'll have to hang out for a bit. But once again, you need to consider how often this is an occurance for you. For some people, it's weekly (or daily!). For some it's once a month or once a year. I agree that we're not at the place where from cost savings alone, it is maximally effective for everyone, but I don't think it's unrealistic for a very large portion of Americans.
