I don't expect players to be using the lifestyle generator much, if at all (except perhaps with the previously mentioned spoofing). If they are it's because they didn't take the time to search out exactly what they wanted and if it happens that their new safehouse is aspected against them, that's the way the cookie crumbles.
When the GM uses it everything is always up to him. For instance, I'd never (without a great reason) have an NPC shaman living in a hermetically aspected home regardless of what the generator told me. It'd be aspected towards him. I'd probably always pick the aspect unless the occupant wasn't awakened at all, in which case random is fine since they probably don't even know it exists.
