I'd agree with you if that was an alternating current charger. But with a direct current charger, you're not tied down to the charger for 4-7 hours at a time, and in fact in Japan they already have a DC charging standard, found on the Mitsubishi MiEV and Nissan Leaf: the CHAdeMO connector.

DC or AC doesn’t matter, it’s all converted to DC before it goes into a battery. I used amps as a generic shortcut that most people are used to. It is the wattage and total joules that you are pushing that makes the difference. While you can push as much energy as you want into one car, one time, in a lab and if you take over the grid, i’m telling you you aren’t going to convert any non-trivial percentage of cars to electric in that time frame (2025)without blowing the grid or blowing the cars or both.
