How could you tell that it was the real thing, and not a knockoff? Or let's say you wanted to make an investment in a multimillion-dollar work of art like a painting? Or sculpture? How could you guarantee that that work of art was actually done by the artist they claim? Or that it wasn't stolen? Having accurate information and a way to verify the sources of things when you're dealing in a situation of a transaction of value is essential. You need to have reliable systems that you can trust, which are tamper-proof.
