Depends on who outguns whom.
Would you like to test your chances against people so dedicated to theft, all they do with their time is find the deadliest weapons to do you away with, while you raise a family and a living. There are no pooled-resource institutions like a government-controlled military to protect you in an anarchy.
I don’t suppose it would take much before a few friends go together and when hunting, mercenary style for such thieves. They might be inclined to go too far and wipe out the entire brood. That could be a problem if the thieves persisted with such behavior.
