The value you receive from forcing JS (anti-fraud, tracking, feature enhancement) is orders of magnitude more than the value you lose from the no-JS users who leave your website.

There's way more active IE 11 users than genuine no-JS users, in my experience.

I agree! What I hoped to showcase in this post, is a way to support users without JS, while not changing how the web app is built. You would still _develop_ the site using JS :)
