Re: relational reasoning -- why two tables and not one?

The only misunderstanding I can see here is the one you are spreading by attempting to establish a relationship between a logical design effort (a process called normalization) and a vague implementation physical performance concept related to a direct image systems's ilmitation called scaling up (related to the increase in time of number of physical rows stored on disk and its impact on response time).

Since you obviously ignore the difference between the two concepts (also called independence between the logical and physical layer of database modeling), I doubt that anything you are posting will add anything of value since your premice is based on utter ignorance of database design...
