Wired networks used to use a sort of timeslot based system, we called it token ring. Then we discovered that collision detection and backoff could work better and have no central authority. We call it Ethernet.

No, Ethernet was cheaper not faster. And you're talking about 15 years ago.

Current Ethernet products meet those requirements already in a chip that costs <$10.

Current Ethernet chips that you might find in a NIC handle the original half duplex spec, which offers no protection against people trying to "cheat." They also handle the much more popular full duplex mode of operation that requires either a point to point connection with another host, or a connection to a switch.

Ethernet switches and layer 3 switches are the devices that control traffic flow and isolate one host from another. And they are expensive, and centralized.

Ethernet's modern reputation for speed is based on using switches not hubs.
