Later, having kept the stupid lock, I found that it would open easily if pulled - with no key. It was defective.

You should have checked the lock immediately when you got it.

This little charade the military does with locking lockers is to teach recruits security.

If one can't even secure a locker, how in the world are they going to secure anything else?

It also teaches following directions.

Being detail oriented, following directions, and securing property can keep one alive in many circumstances, military and civilian.
