When your freedom to steal is met by the property owners freedom to shoot you, how ofter do you think you’ll steal? How many bullet wounds can you survive?
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.
