Your government does have various authorities over what you put in your cupboards though. like, you can't just put a gun in there (actually I don't know where you live but that's true for most countries). You can't just get in a car.

Anyway, ultimately it's best effort. No security is flawless, but if it stops 99% or more of cases it's better than 0%.

Cases of what? Beer in an unlocked cupboard? Porn on an unverified computer?
