Realistic answer to all of those would probably be: "... then this user won't be able to load ads, so I don't care about them anyway"

I find this point of view somewhat tiring and kinda showing a certain amount of detatchment from the general population of internet users.

Avoiding JavaScript in all but the most simplest of use cases is going to leave you with a lackluster user experience.

I keep JS disabled by default and only enable it in certain situations. If your site doesn't work without JS and I try to view it I am probably just going to leave.

Wow. I did not know there were so many non-js environments out there!
