I don't see this effecting my life in anyway. The man needs to go to a judge to find out my twitter identity.

e.g. I'm your next door neighbor or a coworker, I don't like you. I contact the authorities (or maybe I am an authority) and I say your a threat to yourself maybe others. "They" (we) now have the law and motive to go get you, without cause. For no real reason either as you haven't done anything other than annoy me.

I never did get your twitter handle. What was it again?

b.t.w. this is not a threat, just an example.

It's a feel good argument no doubt. But power like this is just waiting to be used and it will be ABused.
