Dave, I am about to give up on trying to make you understand. All I have been saying, and all that some others have been saying, is this: the code does not forbid it.
Read the book. The words are not there.
This is not a matter of interpretation. It is a statement of fact.
But there are words that declare that the NEC is not a design manual. If you want to learn how to design residential wiring, you have to go somewhere other than the NEC. If you want to find out how many circuits should be used to power all the lights and receptacles in a house, you have to go somewhere other than the NEC. I did not wire any houses, as you have done, so I learned in a different way than the way that you learned. I learned to design residential wiring by working for an engineering firm that had residential clients. I have also designed wiring for hospitals, prisons, commercial buildings, office buildings, marinas, tug boats, tankers, passenger ships, and a host of others. I don't put more than 10 receptacles on any 20 amp branch circuit. In the offices and cubicles of office buildings, where there will be computers on each desk, I limit the receptacles to 4 per circuit. But that was a design choice. I didn't choose to do that because the CODE told me I had to. I chose to do that because it is what I believed to be the right thing to do.
That said, if a word does not appear in the NEC, then by golly it is not there. Once again, all I have been saying is that the words are not there.
By the way, to save you the trouble of looking it up, here is "Charlie's Rule." Although I have claimed the copyright, I have also granted permission for any Forum member to use it for any non-commercial purpose.

With my permission, Mike Holt has published a version that I revised for the purpose, and he placed it on stickers that he passes out free of charge. Here is that version:Charlie?s Rule of Technical Reading
It doesn?t say what you think it says, nor what you remember it to have said, nor what you were told that it says, and certainly not what you want it to say, and if by chance you are its author, it doesn?t say what you intended it to say. Then what does it say? It says what it says. So if you want to know what it says, stop trying to remember what it says, and don?t ask anyone else. Go back and read it, and pay attention as though you were reading it for the first time.

Charlie's Rule for Reading the NEC
It doesn't say what you think it says, nor what you remember it to have said, nor what you were told that it says, and certainly not what you want it to say. If by chance you are an instructor, it doesn't say what you have been teaching that it says.
Then what does it say? It says what it says! So if you want to know what it says, stop trying to remember what it says, and don't ask anyone what it says. Go back and read it again, and pay attention as though you were reading it for the first time.
If you don?t like what it says, then get involved and try to change it. In the process, you might discover that it says exactly what it should be saying.
