...you will need around the clock lookouts guarding your perimeter, whether you decide to bug in or out. Two people wouldn't last a week trying to just keep up with watch duty, much less with other chores like cooking, water carrying, wood chopping and carrying, and shelter, in the case of bug out. ...
I'm sure 11B will chime in if he has anything to add... But I think you're spot on.
Maintaining a long term 24/7/365 OP is at probably a squad level task. Typically at an OP you'll have one person on lookout, one person on admin, and one person on rear security. They rotate jobs throughout their shift, and need to be changed out every 12-24 hours.
Effective maneuver with protected persons (kids, non combatants, etc), or basic three vehicle convoy ops, requires at least five armed and competent trained personnel, minimum (two buddy teams and a close protection person to shepherd the kids). Even to execute a basic "break contact" drill and leave the area needs at least a team of four or five.
With only two people the plan should look a lot more low profile, covert, and non-confrontational... Technology and careful planning might be able to mitigate some of the issues with low numbers. I imagine cameras, trip flares, dogs, and intrusion sensors (motion detectors, etc) are useful force multipliers.
