Bank robbers are much sexier than sceenplay writers

Last night I watched the latest Spike Lee joint, "Inside Man." It's a movie about a robbery, what the ringleader and mastermind calls "the perfect robbery." And in the opening scene, during a Five Ws monologue by said robber, he states that the "why" of the robbery was "because I can."
OK. Let's think about this for a moment.
We got this guy named Russell Gewirtz. And he's a writer. He's in the shower one morning and slips and hits his head on the sink and when he comes to he has this idea, an idea for the "perfect robbery."
He spends the next few weeks writing a screenplay about the idea, calls it "Inside Man," and eventually Spike Lee directs it.
My question is, Why the fuck didn't he just rob the damn bank?
I mean, he probably got a few hundred thousand, maybe a million dollars for the script, certainly advanced his career, but he didn't get away with a truck full of cash.
Screenplay writer: stuck in traffic on Sunset Blvd. arguing on his cell phone with his agent.
Successful bank robber: sipping cocktails on a remote beach next to his napping supermodel lover.
Or better yet...
Maybe he could have sold the robbery plan to a high-paying crime network. I'm no Hollywood buff but I think crime-networks have as much if not more money than film producers. But I think they have the same amount of cocaine.
It's just so boring when art imitates life. What happened to life imitating art?
We've all seen "Dog Day Afternoon," now that was based on a true story, a bank robbery gone horribly wrong one August day in New York. But wouldn't it have been better if they filmed "Dog Day" on that hot afternoon?
Imagine this: "Inside Inside Man: A Documentary."
Russell Gewirtz should have implemented his robbery and filmed the whole damn thing. That's what's up.
Rob the bank and make the film.
No one thinks outside the box anymore.
