The example for transport encoding doesn't seem all the more simplified than things as they currently stand. Sure, the field names are a little shorter and easier to read, but there's still a lot of (necessary) complexity in that encoding.

The OSI model of the Internet is built around being extremely fault tolerant and extremely generalized, so that anyone can connect any device and expect a reasonable amount of functionality. Sure, protocols could be simplified or refactored so the topics are easier to approach, but I don't think the ideas presented in this post would bring about a large degree of simplicity.

Also, simplifying the protocols, even by a huge degree, would not substantially grow the proportion of the population that understands them. People work to understand the OSI model out of necessity, not convenience.
