If you even made it there in the first place.
People don’t think about ambush potential or that not everyone would be happy to see them arrive.
That's why I smile when people talk about making their own little hideout, like technology somehow changes the lessons of human history.
What would actually happen, in short order, is what happened in the past - the establishment of fort-towns, based (in all probability) on shared religious or philosophical principles, and run by families and blood relations. And while I'm sure there'd be a lot of bible thumping, I'm also sure there would be a lot of predation of "others," just like in the past.
Past, hell. Just like now, everywhere. People take the tiny bit of civility in the world far too casually. Each tiny mark of respect people show each other was reached through the blood of many in the past - and can be lost again, far too easily, if people don't treat it as the precious treasure it actually is.
