Actually, I will state I can partially understand the position and I don't think it is wholly greed considering stunts some people will do for "kicks."
There was the guy who did the fake death notice about a co-worker on Wikipedia.
There are people who do weird things on MySpace and Facebook.
And in the past few days I read about a new "kick," sometimes used for revenge even by criminals, called "SWATting" where you contact the police through the Internet and make false claims of commiting crimes at another residence. One example, some teenager in Washington state called as if he was in Los Angeles so a couple and their kids got woken in the night and arrested. There's a guy in Medina, NY who was hit 3 times with this.
Licensing I believe provides some measure of protection from things like this.
