I'd rather live outside
It can be argued that Frank would rather live outside because it allows him to find solitude and peace, which may in turn lead to peace.
Or, it could be a reference to his individuality: Frank wants to remain unique in a world where everything is being replicated and copied.
Perhaps, Frank just wants to be alone.
Also, “outside” has quite natural connotations. You can imagine the freedom that the natural world can grant.
