That's because lockpicking is often done in sport. It's a challenge and each one is a new but similar puzzle. There are a number of professionals who enjoy the challenge of breaking into locks. It's also a good opportunity to teach people just how bad most locks are [0] [1]. You also learn that Masterlocks shouldn't even be called "locks" and that locks only prevent opportunist thieves [2]. Also, you do want professionals who are able to open your lock if you ever lose your key. They have to practice somehow! :)
