Arguably, using React where a static HTML with maybe a little bit of vanilla JS would do, is code golf.

HTML and CSS are not bytecode. They're high-level abstractions, hiding a very complex renderer underneath. Sometimes you need to build another tower of abstractions when this doesn't suffice - like when you're trying to build an application with complex GUI in the browser and you need an adapter between DOM and a more suitable GUI pattern. But displaying text and images communicating a message is not one of those cases.

We do not rebuild the tower of abstractions for every site that uses them. I do not personally implement React from scratch when I use it for any of my sites. I get all of the benefits for none of the effort. You do not seem to acknowledge factors other than straight up performance, as is evident by what you are picking and choosing from my comments, so obviously it is not attractive to you.
