There are many practical reasons to limit the scope:

* keeping at least minimum quality standards

* avoiding abuse by storing your files disguised as some "knowledge". At some scale the organization is not able to check even for a trivial instance of abuse.

* abuse legal problems by publishing illegal content (again, nobody will be able to do even basic checks if there's no limit)

* if anything goes, you get limited by physical needs like storage

> If you must, layer curation of what is notable on top of that.

Wikipedia is the curation. Store the non-curated data elsewhere.
