And server side rendering can be as ugly, it is just less visible. We can be really lucky that there is a universal language on the client side for web browsers. Even if it is often abused, it is very much worth it.
Maybe not the most elegant language, but probably one of the fasted to develop with.
Do you genuinely believe this is still an open question?
I won't dispute the argument that maybe it was a mistake, but to me it seems indisputable the ship has sailed.
I might buy the argument that any "mandatory" websites - government, library, academic - should be operational without Javascript.
But in the casual or entertainment domain, noone is obligated to provide their users an operational Javascript-free website. If you can't read something without Javascript, that's a you problem.
Some websites don't function without JS. I either enable it on a case-by-case basis, or avoid those websites.
the 2000s and early 2010s era internet ("Web 2.0") was richer with Javascript WITHOUT all the gargantuan trackers and auto-playing videos.
