I have a feeling one day public titles, marriage, and criminal records will be in a blockchain ledger, and it'll be impossible for government to order them expunged. The way the governments are handling this is trying to impose secrecy with security through obscurity. But the public records exist somewhere, and anyone wanting to do a background check will eventually be able to track it down.

Imagine this case was instead about a Wikipedia article about this guy, and Wikipedia lost the case and was ordered to revert the article and expunge all edit history. Due to the way Wikipedia is cloned by many sources, and preserved by many archives around the world, it will become increasingly problematic to erase information.

If the government can go around ordering archives to expunge truthful public or historical records, it's very problematic IMHO. The notion of truth and objective reality is already under assault since the 2016 election, and the deep fakery and trolling bots will only get worse. What few institutions we have online that can try to weed out and present consensus truth would then be suspect if governments gain global jurisdiction to make edits.
