I would argue that privacy is a need.
"...not a need"
By what criterion do you define a need? I've suggested some in my post that could easily be deemed a necessary requirement to require JavaScript to be turn off. It depends on one's circumstances.
A lot of visually-impared users have to disable javascript to minimize pop-ups to use a braille terminal.
Don't expect typical web developers to care for 1-2% blind users when they've often ignored browsers with 5% or higher market share... Most don't understand that a one-time effort to get the last few % in revenue is worth it.
Javascript disablers (and I have full sympathy as a dev. myself) are doing it by choice which is totally fine but it is still a choice, not a need.
