This is getting overly pedantic. Opening comment said that you'd need absurd amounts of mass to accelerate a person to near light speed. I said that the velocity of ejecting that mass mattered. That if you could push out mass at speed of light, you'd need a lot less mass. Not that you'd push out the same mass at speed of light. Or that you could arbitrarily push things out at speed of light. Sheesh.
