Yes, Arpanet, and the beginnings of TCP/IP were written by engineers/companies working on DOD contracts to build a communications system capable of surviving a nuclear war (literally, routing around nodes in the network that might no longer exist). The bureaucrats weren't designing it, they asked for a system to be built meeting specific requirements. The design work was done by engineers and academics. And once it emerged from military use out to "civilian" use, basically every standard that controls how the internet works, since then, has been done by RFC - a process where someone (person or company) proposes a protocol or a change, and it is debated and tested thoroughly before being possibly approved.
The point being, it gets designed by engineers, not by politicians, it gets implemented by consensus, not by mandate, and it gets replaced as technological improvements merit, not when someone passes a new law.
No government (thus far) says, for instance, "we've decided that POP is the proper way to handle client-to-server email transfer, so we're legally mandating that to the exclusion of all other protocols" (which is a good thing, because IMAP presented a superior protocol for that task and largely replaced POP).
