Plenty of expatriot Americans out there all over the world and no doubt expatriot Austrians, Russians, Chinese, etc. If elsewhere or multiple elsewheres is how you want or need to live that's a fine choice. Won't work for me at this stage of life, too old for those choices.
Now that bugout to home concept has always appealed to me

did it for 15 years, now I just mostly stay home and make trips to towns for regular resupply. My little closeby town of 2000 used to have its own power plant but the city council of the 90s and early 21st century sold that off, same with the town owned water plant. I bet they regret that but then again they now buy from the nearby town of 75,000 and it may work better for everyone. Though my exurb is 10 miles from this town it is where I draw my sense of community. I look for things like, local businesses to support because I need those things anyway and something like 60% of any dollar spent stays within a few miles of where it was spent IF it doesn't go to a non-local corporation. There are schools, churches, dentists, doctors, brewery, restaraunts, bicycle shops, vehicle repair, stone quarries, fuel, groceries, all within 10 miles of my home. That's where community lives, wherever you live and share with those around you.
Everything risks collapse. The cities can work, see what the Cubans did in 89 - 93, it takes massive changes, but it can be done. Suburbs can work, if the same level but different kinds of massive changes occur (not as likely in my opinion), and living near or as part of food production is always a good strategy for staying fed. If you are planning to bug out, do it now before the SHTF and become part of your own future. Why wait? do it now while things are still relatively easy. Wherever you plan to bugout to you will not be alone, somebody else is already there so forget the Jerimiah Johnson man in the wilderness stuff, its not gonna happen in my not at all humble opinion. Go where you want to be and be part of the community.
