Yeah, but some of us are not aware that the Nigerian prince isn't legit, and that's all the 409 scammer needs.
Besides, that doesn't make this less clever, just marginally less effective on a per capita basis. The next iteration of the scam--perhaps augmented by your constructive criticism--will do it through the mail. You can send a check or money order to [fake address], or you can just pay it like most people pay parking or moving violations these days, online. If the scammers are really smart they'll tack on a $5 "convenience fee" for added verisimilitude.
At least in concept, I'd say this scam/hack deserves a fair amount of grudging respect.
