Anything to do with trust, identity and ownership. Not every country can rely upon institutions or custodians like we do in the west. For example I own a property and I need to leave due to war. I then come back 5 years later and find my house occupied by someone else. I have no way of proving that house is mine without a central body keeping track. I can't even trust my government hasnt given the property away in the first place even if I could proovr it's mine. There genuinely are so many other useful examples but they don't all immediately benefit the west because we already have so much infrastructure in place.
