Earlier quoted context omitted.
You are arguing against a strawman - no one is claiming otherwise. All paul_irish wanted to show is that people often use jQuery without realizing that most of what they do is also possible with the current browser APIs. jQuery does a ton more (animation, ajax etc) - the point was not to "rewrite jQuery in 10 lines" (that's Zepto)
Um, isn't the point of Zepto a modular jQuery that may not support 100% of what jQuery does but it tries to at about the same speed (or better)?
But honestly, if you load jQuery from a big-time CDN, chances are your users already have it cached and don't need to load anything.
