I think you have fundamentally misunderstood my point.

Let’s say I buy a widget. How can I trust that the widget will arrive? That it will do what widgets do? That it will not break? None of these are payment issues, but they might call for a refund. How can I get a refund? How can the refund system be resistant to abuse?

The answers we currently have are “the law”. If the law functions, I don’t need a trustless currency.

If I have a choice between math or "the law" as for which functions more reliably, my bet is on the math.

How does your maths enforce arbitrary quality control assurances? How does it guarantee refunds for breaches of contract?
