There are so many homes and places abandoned by people and owned by banks...how it all started was homesteading...people were allowed to claim land and property but they had to work the land and fix it up. If the banks go down then no one owns those mansions, homes or land. Then homesteading wold be an option, to stake a claim and work to make it a place for people that serves either groups, or to grow food and so on....Staking a claim of the land and not thru a bank.
