The web isn't. Doing these with the web requires at least a server, a programming language, and a database. Anyone can easily view a webpage, but you need a separate editing system to be able to easily create. Even then, there's probably no "View Source" for most of it. Without a big fancy editing system, there's a huge learning curve between "hello world in HTML" to sharing with your friend, creating a template shared between pages, or saving data between sessions.
Of course, that's modern web architecture. The "original web architecture" had no XHR, or even JS. It was 5 years before you could click somewhere on the screen and have it do anything other than "go to another HTML page".
