Sure, but most sites don't go to such lengths, and even captchas can
be defeated if you're trying to scrape a specific site and are willing
to spend effort on the particular captcha generator that it uses.
Plus there is always www.captchasolver.com (!).

Certainly true, but there are times when you have to pull stuff out of
the JS.  It's usually possible to do that without actually
interpreting the JS, but an interpreter would make it a lot more
convenient some of the time.
