I never said the home would be the primary charge point, you wouldn't charge like this at home, but at a charge station.
I'm implying that these are the specs necessary for an electric car to truly be taken seriously as a replacement for a gas vehicle.
Furthermore, charging at a higher voltage, say even 720 volts (about twice the current roadster's voltage) gets you down to 500 amps to charge a Tesla in 10 minutes, which is manageable for cables. Charge stations could have a reserve/buffered system they can charge from that way they wouldn't be hitting the grid all at once if 5-6 cars show up. You could do a similar thing at your house (basically a large UPS)

The battery swap thing is a pipe dream, IMO.
