I felt this way when approaching my personal site. I was falling into the Gatsby trap and then realized all I needed were HTML, CSS, and a few JavaScript files. I think you see over-engineered solutions as a result of career driven development and the hype around these libraries/frameworks on forums/social media.
My personal website is still based on PHP, after using XML/XSLT for a short while, I rewrote it in PHP 5 shortly after it became available. While at work, it has been mostly Java JEE/ASP.NET since they exist. When I play around with WebGL, it is all JavaScript modules and script tags, nothing else. No babel, no webpack, no npm, nothing, just browser standard capabilities. Fully agree with your point of view.
It just feels great that I could just immediately start fixing things on any computer should an issue pop up next year or so, without worrying about dependencies or some build step being broken etc.
