I think the reason it is like that is because there were many problems with JS "back in the day", and so people felt they had to come up with solutions.
Just look at Svelte. It's a library about compiling JS to get back to the "just JS" days. I mean, it's more than that, but it's about reducing runtime complexity. So another way to think about it is that writing "old style simple JS" is so convoluted that the author felt the need to write a translation layer from modern frameworks to old style JS. Sort of a mindblower to me haha (though, I love and agree with Svelte, to be clear).
The great thing though is that you can still use plain old JS, right? Nothing has changed for you if you don't want it. So is there really a problem?
This "modern web" stuff is just people solving problems. Some of these problems are the fault of old JS/web. Some of them are problems of our own making. Remember how amazing modern UI frameworks were? It's because we had PTSD from horrible jQuery codebases. A problem of our own making.
So stick with what you like, and other people can use the more complex stuff. It's a win win, no?
I did classic server side rendered apps, but experimented with pure JS apps early on where the only way to get persistence was to store things in cookies. The "app" was just a html file on the desktop that you double clicked on to open in the browser. Then came AJAX. and during the last fifteen years more and more pieces have fallen into place to make web apps more viable, like service workers, local storage, add to desktop, etc. But JS apps are much harder to develop compared to server rendered app, because you have to manage state, while server rendered apps are just a snapshot of the database.
