When I setup camp I just use the the established site for fire time activity. I setup my hammock off away from it and try to keep my good gear out of sight. I'll setup my fire pit and maybe leave a book or something to let people know someone is around if I'll be away a bit. I seldom go far from camp but sometimes I do for a short loop or hike. This is why I like the camo Clark. With a little distance, you can disappear into the background and prevent people from noticing that you have some expensive gear.
Stealing a persons food and essential equipment on the trail is some downright disgusting behavior. You could leave a person for dead like that with a hard storm or cold weather.
