Basically with trust, trade is unfettered.
We trade productively with trust and we all prosper.
I see this in my life. I have good trust in costco, and I buy there with very little friction/mistrust. I know a bunch of things - they give me a decent price without trickery (unless you count giving my money back as rebates), they vet the products they sell, and they have a great return policy if I don't like the purchase for any reason.
meanwhile buying an airplane ticket, making a hotel reservation or getting a tow truck. That is a low-trust high-nonsense situation that makes me unhappy from reservation to checkout, almost to the point I dread travel. I do travel less, and I'm less spontaneous.
