To my mind, less privacy is inevitable, so I feel it's better we face the issues/challenges head on sooner, when it's manageable, rather than later when we might be overwhelmed and not have adequately addressed the pitfalls.

I don't see how your example is relevant, Ken. Just because an e-mail address is available to an admin, doesn't mean that there's any public accountability for the aliased poster, which I think is the point of having a real name associated with public comments. Am I missing something?

Also, it's not about making people change, per se, it's about making people act online more like they'd act in public. It's about aligning public online with public offline to make online a better place for everyone. There will still be jerks and asses - that's human nature - but if there's a chance for a potential repercussion or two, maybe it can - even in small ways - improve things.
