You're absolutely right that it is possible to get close. I think my main point here, (though I probably didn't cover this well enough and I was being somewhat hyperbolic, I guess), was that 'damn close' is unfortunately not the default on web, and it's actually really, really hard to get there.

Sorry for coming across as a sales person. Someone tweeted about a previous presentation of mine in the past asking "who the hell is this marketing guy they had do this talk". I assure you I'm not in either marketing, or sales, I just get really excited sometimes.
