There is ways to set this up with current plug-ins. I use Rust Essentials on my server and as such I can setup safezones where players cannot kill other players while in the zone. Buildings also cannot be destroyed in the zone. People in the zone cannot shoot and kill players outside the zone either as to prevent abuse. I believe Oxide also has a plug-in that does this as well.
Thanks for the info! Sadly, I'm not an admin, just a player on someone else's server, so I wouldn't be able to set up safeguards. I kinda wanna see how people would treat it in a vanilla setting, see if on a community basis we can get everyone to treat the area like a, "safe zone," without actually setting up mechanics forcing them to. (Social experiment :p) If I were an admin I'd definitely use one of those plug-ins though!
