Well, I agree with you, but to be honest it's not Javascript, it's Web APIs gave a lot opportunities to surveillance capitalists.

But even if you turn off Javascript, you are not invisible or untraceable, you are just getting a little harder to be tracked. I don't wanna name anyone, but there are tons of famous websites that tracks by including <img> tags and referencing pixel trackers.

I usually browse with JS turned off, it's blazingly fast, and, well most websites work without any significant drawbacks.
