It is okay to do business with people you don't trust, but the crux is that pow/pos doesn't actually solve most of the substantive trust problems. Eg: all of the weird supply chain nonsense around blockchain. You can keep a ledger and so on, but if there's corruption/theft in the physical warehouse then the ledger is worth only and exactly the disk space to which it's written. No amount of distributed consensus will change anything about the fact that Joe's cousin's friend heard about the shipment and stole 10% of the bulk good and replaced it with dirt to make the weights match. The problem of doing business with people who you don't completely trust is very real. However, blockchain offers no solution (except and unless the thing you are trading is something that literally be placed on a blockchain, ie nothing physical and nothing that depends on a legal system to enforce).
