I found the following in September 1963 MRR. Author is Charles Small, a pironeer in HO, On3, etc. IMO it's a summary comment on the recent foofaraw about Sellios and Furlow's layouts, especially the last couple of sentences.
"When you come right down to brass tacks, it's all fantasy anyhow. I defy anyone to reproduce a real railroad in anything less than full size. The function of the model equipment and scenery is to assist the process of imagination. The closer a model comes to reproducing a visual image of the real thing, and the closer operations approach the actual, the better is the imaginative stimulus. That is, of course, if you are really pretending to run a railroad. But I think some people regard a model railroad only as an entity in itself. From that standpoint you don't have to worry whether it follows a prototype or not."
