Take crypto out of the equation, what are the implications of the fed issuing a programmable currency? Many financial services would become obsolete. What do I need a stock broker for? What do I need a bank for? You have Wall St and other sophisticated investors profiteering and competing against the general public, devaluing our purchasing power, making leveraged trades because they know the public will hold the bag…
The majority of economic activity is not "programmable"--if I order a ship load of steel from some country, how is that contract going to be enforceable/verifiable with cryptoeconomic techniques?
Presumably the shipment has a series of checkpoints, which add some amount of traceability. There's also the potential for insurance for blockchain contracts.
I only recently learned about oracles, but I suspect we're only getting started on unlocking the potential of blockchain.
If there are oracles making the progress at each checkpoint along the way available from the blockchain, and insurance contracts for potential disruptions at each stage, your contract can ensure payment on delivery, and the supplier can be insured against any disruptions.
