That's fine, though. If you make the lock on your front door more secure, the weak point is now the latching mechanism, the door frame, or the door itself. Or perhaps it is your sliding patio door, that can be levered. Maybe you left a window unlocked. Or your garage door has a code that can be MITM'ed or brute forced.
The thing that saves most people is that there is really nothing worth stealing in their house. If a fence pays 10% of retail for stolen goods, I'm not certain there is any single thing in my home worth more than $25 to a burglar, other than the emergency cash. Rather than take the TV or any of the decade-old cap-rot Dell computers that have been re-capped, someone would be better off stealing all the meat out of the fridge, because at least they can eat that.
