Ah, so you imagine that this happens to all the people around the world that hoard gold, Jewelry, and other valuables at home? All 2 BILLION of them?

The difference between a criminal that will take no risk to pilfer through boxes and one that will risk his life breaking into a home that may be armed is extremely different. 

You really should think through carefully what your actual risk profile is. Everyone should, but you more than most.
