That is not the authority that I meant when I used the concept to explain how the Bible's canon is based on the existence of authoritative texts endorsed by authoritative sources.
You can make an edited version of the original Hebrew and Greek scriptures with whatever changes you want. But no one will agree to call it The Bible, because it does not match the text endorsed by the original authorities.
Same as how there still exists a Sherlock Holmes canon based on Doyle's work, even though you can legally write whatever you want even in contradiction to that canon.
No one holds authority over the original texts. There is authority over translations though. But the original is open source with no license.
