Well yeah I can see the public geting a bit upset if we start creating and
storing tens of tons of anti particals in our starships Bose-Enstine condesit
tank.  Especial if we do it in low Earth orbit.  ;)

Materials are harder to get on a planet then in space (water, ore, air
subcomponents) spining for grav isn't hard.  Probably no real chance of
finding a planet with 1 g, right temp range, and non toxic but breathable air
