We have dispersed camped all over the country and can say, from our experience, there is a different approach depending on where you are. In the south, retribution is common and accepted even though it's somewhat changing due to demographic shifts. If someone is bold enough to take someone's stuff or site they are bold enough to suffer the consequences, or they are stupid. Someone stealing your site doesn't warrant death but removing all of their equipment to re-setup your own is acceptable, or running it all over with your jacked up truck (a funny thing to witness) is good old fashioned entertainment for everyone else around. We would say it's akin to an honor system or code but in reality it is more related to self-preservation. There is a reason "hold my beer" and "Florida/Georgia/Alabama Man" are popular. Even pretentious west coast/north east vacationers are wary of which species they may encounter or unintentionally offend. There are much worse things than the Deliverance treatment, compounded by all the spectators drinking beer...albeit, no longer Bud Light.
