There's nothing preventing you from building your site out of manually crafted HTML pages (I do for instance) and I would even dare to say that it has never been easier to do so (things like Emmet make it really easier to produce HTML content from your text editor of choice, services like cloudflare pages or vercel take less than a minute to go from local to public).
CMS made it easier indeed for not-so-technical-savvy folks to push stuff on the WWW but is it actually a bad thing? At the end of the day, it's the content that matters in my opinion.
