You’re proving the other persons point - the reason why the a thief doesn’t trivially pick locks isn’t because of the lock, it’s because it’s illegal and there’s a consequence.
consequences for doing something illegal never stopped me from picking a lock, actually. they've only stopped me from stealing
Yes it's illegal and there's a consequence but do you care about it after you've been robbed?
You could say the same with a lock. Do you care once it’s broken?
The point of a lock is that it's something to break. That takes skill and visible equipment. The more skill yoo require the more likely the smart guy would do better things to earn money than crime. the more visible equipment the easier it is to track.
