It would also be faster if we referred to files by their inode numbers. But we have filenames, and I don't want to speak for everybody but I think people like them.
Actually, we do refer to files by their inode number, not by their name. The system uses the name to lookup the inode number, and then use the inode number.
Maybe I misunderstood you initially[1], but you weren't proposing to keep the numbers and use a lookup service for the name. AIUI, you proposed to replace the number with a name, no?
In which case, absolutely no one is proposing to replace inode numbers with names, so inode numbers/filenames as an example does not validate or lend support to your proposal for replacing port numbers with names.
[1] I'm on a personal quest to stop misunderstanding people in a way that reduces the strength of their argument. It's not going as well as I though it would, and I still do it sometimes.
However it only works on your machine.
If you want to have it work on your local machine, DNS SRV records on your local network would work.
The proposal to use names and not numbers breaks down when you want the rest of the world to follow suit, because it's not technically possible within IP, only on top of IP.
This is exactly my point.

In which case, refer to my original response to your proposal - it's not practical to slow down every networking device in the world by a large factor.
It's like asking "why aren't we commuting at 1/3 the speed of light?": it's neither feasible nor practical.
Sure, it's possible, in that the physics involved make it possible, but not practical, because the limiting factor is not the physics involved.
