Wait - you trust humans? Just like that, without a legally enforceable contract that guarantees you certain rights in a court of law, to be enforced by the state, if they renege on their word? Astonishing!
Nah, that's still trusting humans. Blockchain backed by Proof of Work was invented literally to solve the trust issue: turns out, trust can be dominated in energy, and all you need is to burn the equivalent in kilowatt hours to no longer need trust.
(Note: the kWh/trust factor grows over time and with use.)
