I have, for the first time, had an issue with thieves. The particular one I'm dealing with right now waits until I'm logged out to loot my base, every night.
I had the thought of waiting at my base and watching to make sure no one stole. But then I thought--even if I caught them in the act, what could I do without rage? I have no way to stop them from stealing, even when I'm there, as long as they have Theft and I don't.
Aside from physically forcing someone back with structures like palisades and fences, how are you supposed to defend yourself without making yourself a criminal when something like this happens? Can I theoretically only do nothing but watch as they waltz in and take everything?
