IF YOU APPLY THIS PRINCIPLE GENERALLY, WE’D LIVE IN THE LIBERTARIAN PARADISE OF MY DREAMS: Members of Congress can’t possibly regulate Facebook. They don’t understand it.

The thing is, they don’t understand much of anything well enough to regulate it. Firearms, the economy, education — you name it. But the press that is enjoying mocking Senators as old and out-of-touch because they don’t understand Facebook’s business model — which the press doesn’t either, really — won’t extend that understand-it-before-you-regulate-it principle in general, because in general it supports big government.
