The kinetic energy in a 100 ton mass traveling at even a "mere" 1% of c
is... considerable.

Long and short of it:  space is big, really really big (down the road to
the chemist, etc etc).  Any form of travel energetic enough to get the
PCs from point A to point B in a reasonable amount of time can probably
be converted, somehow, into a big enough BOOM to absolutely ruin a lot
of people's days.  So it's really really hard to keep WMDs out of the
hands of adventurers, because they "need" one just to get around the
setting.
