The world is complex and nuanced, and any "best possible world" will therefore be complex and nuanced. I did not advocate for the complete removal of all anonymity, which might have prevented important historical events. I advocated for "whatever your idea is should be reflected on your reputation".

In a "best possible world" there is a time and place for anonymous speech. But "I can create troll accounts faster than you can ban them" (which is what we have now) is not on the road to that world.
