Because of NAT, hierarchy (centralized servers) is the foundational design pattern of the internet, and anyone who wants any semblance of anarchy (decentralized networks) must use a workaround that is itself hierarchical and costly. We are all interconnected, but only a wealthy few can truly speak fist.
The issue that ipv4 exhausting and "solutions" around it like NAT are making it very hard for actual users (bussiness, people etc) to get access to public IP space without strings attached.
IPv6 solves a lot of this, especially because IP space is so massive LIR's don't need to be so spare with giving out address space.
The far larger issue we have is that applications are ingrained in a client server mindset, in which big incumbents want to have this architecture because it forces control from the server towards to client. And control usually also means having the data itself, which is where the real value lies.
The sin here is the hierarchy imposed by SSL and its infatuation with server names. Its says: these people are lords, they can wear the server hat. As for the peasants, your client hats are over there. If we catch a peasant wearing a server hat, the browsers will make them look like a criminal.
Our applications have evolved accordingly.
