[Men in Black] Why do agents have to get rid of their personal lives?

There are plenty of people working for secretive governmental agencies like the CIA, NSA or MI6 who have very sensitive positions. 

Why does MIB require their agents to give up their personal lives? Why not just have them work under a cover identity instead?

That's not nearly secret enough for something this important. When someone becomes an agent, their previous life is disappeared. Records, fingerprints, and even other people's memories of that person are all erased or rewritten. To quote Zed, "Your entire image is crafted to leave no lasting memory with anyone you encounter. You are a rumor, recognizable only as deja vu, and dismissed just as quickly. You don't exist, you were never even born... *you are no longer part of the system*."
