"In short, I will show a "This site requires Javascript enabled" message 100% of the time if my site requires Javascript."

That's why we users need replacement/plugin alternative JavaScript engines that will allow users to tweak settings and to send feedback/info back to the website that the user thinks that the site should receive. You or the site can then remain blissfully unaware that what you are receiving from the user's machine is cleverly-framed (disguised) garbage.

Sooner or later we'll have a plethora of such engines and then the tide will have turned.
