V=IR works perfectly well for AC just as long as you measure the AC in terms of RMS voltage and current. For sinusoidal AC the result is about 0.7 the peak value. There would be no significant difference in wire size.
DC is in fact the better way to transmit energy over long distances. The computer I am typing this on is powered by energy transmitted 900 km in the form of DC.
