True, though you could get almost the same effect with the
thermonuclear pulse engines that are already used for moving asteroids &
colonies in Gundam. These devices are highly fuel-efficient and can be
used for years at a time; their acceleration is very low, but after
months of gentle thrust you can reach tremendous speeds.

True, though even the closed colonies are dependent on solar power,
which will be hard to come by in interstellar space. Time to hoard lots
of fusion fuel!

Absolutely no need to do that. Far better to accelerate at a tiny
fraction of a gee using a fuel-efficient engine, like the pulse thrusters
I mentioned above. In order to reach, say, half the speed of light -
after which relativistic effects start to kick in - you'd have to
accelerate at one gee for roughly a year. Accelerate at 1/50 of a gee,
and you'd hit that speed in a half-century. That gives the one-gee guy a
25-light-year head start, but after that they're both covering 50 light
years per century.
