Since we know all analogies breakdown under close inspection, I'm pushing the idea that the best analogy is actually a brief description of the event / idea itself.

So in this case:

Not display www. in the address bar is actually a whole lot like not display www. in the address bar.

And if anyone doesn't understand why that is a bad idea, maybe we should explain it to them, which might require using admittedly imperfect analogies that they can nonetheless understand.
