All the existing systems we have to solve this area are trust based systems. You trust your browser and OS to choose the correct CAs to trust, and they are the ones that validate to you that google.com is Google. Whole schtick of crypto folks is about reating trustless systems. It is trivial to add real world information to a blockchain if you have an authority that you trust, the oracle problem is how to do that when you don't.

Even the Congress example for who is president, we literally had a bunch of people certify fake election results last election and try to overthrow the US goverment. No matter how much you scream that one day the blockchain will be the reality, that goes agaisnt every single judicial and political system we have in the world, and if you disagree with it, I hope someday somebody doesn't hack your house away from you, cause then you will learn why all proper property systems have judicial systems with actual human beings running on human logic with power to do fixes.
