Define rare, and how do you know, it was only in 1984 that the first extra-solar planet was discovered. We have know idea how many "goldilock planets" there may be. But yes, I agree, unless there is a way to jump across space then we may remain isolated.
Depends on how strict your definition of a Goldilocks planet is. If it only means a rocky planet with an atmosphere within the habitable zone of the star, then maybe most stars have one. If it means a planet that starts out like our own (where life could originate in the first place; this is no longer possible), has plenty of water, a moon like our own, a dense atmosphere, a strong magnetosphere, the right axial tilt, a day that's only a couple of hours long, sheltering from comets and other nasty solar system bodies, and all that, they're probably not that common.
Don't get me wrong--there are probably thousands of civilizations, but they're scattered across a universe with a diameter that stretches out for billions of lightyears, and I don't think they'll ever interact in any way.
