Hard to simplify
One can't live a simple existence anymore. I remember one time in Oregon I went up upon a mountain in an RV planning to be alone for a time. Local ranchers came by to check me out, helicopters flew over to have a visual of me, and chipmunks always made their presence felt. So much for solitude.
The maintenance on my condominium is high. To move to another condominium without guards at the entrance would mean being around noise. Dogs, boyfriends, kids would be all over. I'd be living with loose end people so I stay where I'm at, in an adult community, where restrictions abound but keep chaos at a minimum.
How about simply moving into a mobile home, unattached to neighbors, as simple a structure as is around? However, it's totally vulnerable to hurricanes which we get in Florida. It's vulnerable to theft and druggies may become your neighbors.
It's hard to simplify today. You are stuck wherever you are at.
