Ken Liu: Byzantine Empathy - Feasible? Where are the borders to put reall things into blockchain?

So if you don't read yet Ken Liu's Byzantine Empathy I recommend it. Because it makes you think. There are issues that may arise in you, such as: Can we put events in the real world into a blockchain intelligently? how well? and where are the borders?
Spoiler
In the short story, there is a cryptocurrency called Emphatium, it's a for charaty, for small donations. And there are Emp holders they decide is a group or a person who asks things is valid or not. Do they really need those things? So they shoe documents and make video even VR video too. But in the end, of the story, Liu pointed out VR video can be false too. But what if, the cryptocurrency have an app in a cellphone and the app can take a picture and make a video. It can prove that it's not false because you make it with the app, and it goes to the blockchain in real time, for example.

Okay, it's just a thought. In the story, there are far more interesting thoughts, and I don't really spoiler it and explain it how it works so read it...

Thx for reading, and waiting for your thoughts..
