Randomly uprooting and gadding about is easy enough if you stay aloof from any communities in whatever areas you find yourself in and aren't hardcore (or even midcore really) on food production. I don't feel too much inclination to go anywhere as we have a lot of food growing in our yard (and we're planning on sneaking more around the neighbourhood but not sure how or when we'll manage that yet), aquaponics are not easy things to move (we had enough dramas just moving them a short distance across the yard x_x), chickens can be "entertaining" to relocate, hell we have problems just with the cats and dogs and they're generally a case of "get in the car". And we're quite entrenched in the fabrics of our local communities and they're not things that you can take with you for the most part.
I agree, some attachments are more enduring than others.
