Downvotes are deserved. You may not want to see HTML, but the thing is, it impacts performance of the page. Client side performance has direct and measureable business impact. Also, let's not forget, that more and more people browser the web on their mobile phones. Some still pay a lot for bandwidth or have a traffic cap, so every byte counts there. Also, so far mobile phones are pretty restctricted in resources, and if you go over some limit compontents of your page won't be cached and browser will have to redownload them, then see the first point. If you use any kind of DOM manipulation having gaziilion of unneeded elements will slow script down a lot. Once again, on the phones and tablets that is even more important than on desktops. Others already mentioned accessibility. There should never be ecscues for a sloppy code not to metion a horrible code like this.
