So one should dynamically generate the page's markup for every single page view? With the attack surface that comes with exposing your PHP site to the public internet? Are you going to conscientiously check for security updates on your server? Are you going to trust whatever CMS you're using to win the whack-a-mole game of patching vulns (and god help you if it's Wordpress)? Are you going to stand up and maintain your own database server? Can you scale up capacity if you need it? Have you thought about backups? The "all in one package" solution is a lot more complex than you make it sound. I would argue that much of the 80% of the web powered by PHP would be well-advised to utilize cloud services.
