Cryptography doesn't eliminate the need for trust. It merely lowers the cost of verification.
It's a huge difference.

Some people think they can somehow completely eliminate the need for trust once their new cryptographic scheme will prove sound or their new system be implemented.

It's a red herring. If you take for granted that there are no perfect solutions just tradeoffs, you will design it right because you know you must distribute trust in the system *somewhere*.

In other words: verification has a cost, and in real life you always have oracles asserting things you cannot fully verify. We live in a fundamentally uncertain world.

What we can do is accept some fundamental limitations and get the most out of the rest.
