What is the Purpose of Chapters?

In Reality chapters were set up for Very Large Lodges (in square miles) where attending a meeting would require an overnight stay. But it has changed drasticially from what is was intended and in most cases they cause more problems than they are worth. It becomes a power strugle between chapters.
How do I know that this was the reason? We have in our lodge one of the original members of our Lodge and he is still active. AS an adult he served in Region OA Leadership posiions and help develope the idea of chapters.
