The cause of losing your treasure is leaving it unguarded.
Banning thievery isn’t going to prevent your treasure from being taken. You’re going to have to guard it. If you don’t mind losing it, then don’t guard it.
That’s it, that’s all. Nothing else.
My brother worked for years as a state mental hospital technician. He helped care for the criminally insane and violent. That is, until the Liberals closed-down all the mental hospitals because “the patients’ civil rights were being violated.” So they let-out all the criminally insane and violent. You can now visit with them any day at Boston’s South Station and many other lively places.
