Even though a chest can be locked and can not be opened without a key, it can still be broken by any player. This is not to effective, is it?

My understanding is that the locking feature was designed primarily for Adventure Maps, where players would not be able to break the chest without a properly created (as in, spawned with the suitable CanDestroy tags, not manually crafted) tool.
That being said, I can see how this would cause problems for people using this for SMP servers. As an alternative, you can simply use Ender Chests for secure storage of individual player items, though this still leaves sharable locked chests vulnerable, and you don't get the benefit of Large chests.
Could go either way, as far as being intended behavior is concerned.
