I think another reason is that in a 12 volt system with points, there is usually a resistor that drops the voltage in the primary circuit because 12 volts going through the points will burn them out quickly. Without the points to worry about, you don't need the resistor to lower the voltage in the primary, and with the higher voltage in the coil, you don't need the recharging of the coil that the capacitor provides in a points system.
