Ditching TCP/IP and defining a whole new protocol stack would require your ISP to have routers that know how to route this new protocol without IP addresses. Also, every router between the source and destination would have to support the protocol also. That seems like a huge hurdle. We can’t even get mainstream ISPs to support IPv6 in the last 25 years.

Unless the author intends to layer this on top of IP, which defeats the defined goal.

If you did this, you would be running your own “Internet” with only your own routers connecting to each other.
