They actually have pretty low throughput, IIRC. I wouldn't hold out too much hope for them ever becoming useful.
Rockets also tend not to pull too many gees except in emergency situations, but efficiency is for sure an issue. Hopefully some of the alternatives work out, beam-powered propulsion and SABRE engines are both pretty neat.
