If you accept what the system actually does now, and decides to live with it as it is, you just deprecated the original "purpose" and made it irrelevant. You embraced "the purpose is what it does" - to you.
It does not ignore the word. It subverts it, and that's the point. It's the system equivalent of "death of the author", which states that omes a work is written, the authors intent loses relevance and the work must be examined on its own. The aurhors opinion or relationship to the work carries no more weight than any other persons.
That's not "true" in any demonstrable sense, but it can be a useful form of analysis. As it is with "purpose of a system"
