Yet another aspect: In Latin, after the Republic, there's an increasing loss of punctuations and word separators in the written language, and with varying writing directions, as in verses, a distinctive word ending becomes really important. (Which may be a cause for the simplification mentioned in the article.) Now also take the rather free word order into account and it may become quite clear, why forming a relational web using types and repeating the respective word endings is really helpful. The other way round, that this loss of word separators and punctuations had been possible at all illustrates rather well the amount of redundancy and robustness this system introduces in a language.
