Bitcoin doesn't solve any trust problem outside of how many bitcoins are in each wallet.
Even in the very basic ecommerce use case: buyer purchases item online with bitcoin. The buyer must necessarily trust the vendor to deliver.
There's no recourse outside of the good graces of the vendor. There's no chargebacks or third party mediation.
Thus Bitcoin actually reverses the risk assumed by online purchases from the vendor to the buyer.
This is the reason why Bitcoin is a failure outside of niche grey and black market concerns. It is far worse for the consumer than existing solutions that isolate them from transaction risk, and will usually kick back a small percentage in cash back.
