Trust is not always a bad thing, it increases the efficiency and reduce the cost
For example, when you purchase a cup of coffee, you would simply trust the organization that handles the transaction, since they have no reason to fool you and destroy their reputation just for a cup of coffee. It will be absurd to write a contract for each coffee purchase
However, when you purchase a house, the trust of the dealer must be ensured and there must be a legal document behind that purchase. So the required trust raises when the transaction value increases. But still, you don't need all the people from the world to make sure your purchase is valid, a signed contract that have legal status is enough
However, when it comes to money creation, you need all the people from the world to make sure the money creation is honest. If you rely on any single entity, and this entity go rougue, you will have no way to avoid a loss, and that loss is imposed on every user of that money
The genesis block indicated that bitcoin is created to solve the problem at the money creation level, e.g. central banks bailing out commercial banks using money out of thin air. There is a built in payment mechanism in bitcoin to do the initial coin distribution, but user level traffic is not typically a monetary system's task. In above examples, you just need a little bit regulation/insurance on those institutions so that they can be trusted by average consumer
Bitcoin is first a monetary system, then a settlement system, and last a payment system. The amount of trust involved at all these different levels are different, and should be treated differently. Trying to apply the same trust-less model on all these different transactions would result in large waste of resource and extremely low efficiency
I guess you got a point there. Fortunately Satoshi presented us with the perfect soution for money creation and finally we can gat rid of this corrupted financial system!
