The first choke point is the ISP. You are completely dependent on the ISP or mobile provider to get on the network. Once on the network there are multiple choke points around IP addresses, dns, ca authorities, registries and more.

As long as you are dependent on anyone to get on the network it by definition can't be decentralized. Consumer wireless tech is heavily regulated and governments are extremely paranoid about communication channels they don't control and can't monitor.

This is unlikely to change because there are no incentives to develop technology that truly empowers individuals, there is no profit in it, it's a social good. If developed it will be demonized and made illegal, and limited to minority dissenters, the general population is unlikely to go through hoops to get on a network.
