Replaces silly claim about JS being bad

> Ask yourself this: do you really want JavaScript to have the ability to load files from your local file system? Your immediate answer should of course be "not in a million years!". If JavaScript had free reign while operating under file:// there would be nothing stopping it loading pretty much <em>any</em> file it fancied and sending it off who knows where.

This is absurd. There's nothing inherently wrong with JavaScript the language accessing the file system, and one can easily imagine a world where security policy can better manage these things. The reality is that browsers just don't permit it without special launch flags like `--allow-file-access-from-files` in chrome.
