This point always comes up, and it typically shows a lack of knowledge about what you can do with a smart contract. E.g. with a smart contract, you can implement an option on anything and sell the option to a counter party with very little work. How would you do that without a blockchain? One way would be to sell an option on a listed security through your brokerage, but the blockchain democratizes this ability and makes it so anyone can do it for a different set of assets then would otherwise be possible. Like why have digital banking infrastructure at all? What new thing was enabled by digital banking infra? The answer is that nothing new was enabled, but the tech made banking operations faster and more accessible to more people. The same thing applies to blockchain tech.
