Infact I would go so far to say that it requires a constant introspection to evolve society to adapt to its current environment. This would be impossible in a "perfectly" enforced system, or even a vaguely rigid one.
The locks, the speed limits, the restrictions all remind one of how they're being limited; not by their own ability but rather an extrinsic force. I'm sure that this can breed subconscious resentment. I'd question if this is ultimately a good thing at all, but it IS hard to imagine a world without locks
