Re 3., tell me one problem that blockchain solves that a regular db and authentication can't?

  Financial transactions without third party verifying and/or underwriting the risk. That's everything. Frictionless (well, one day) payments.

    Consumers quite like the protections against fraud or loss which they currently have. How does that work without a trusted third party? Similarly, what does “frictionless” even mean? Consumers have very little friction currently and the situation is decent for most vendors. How much better can a new system be, especially one with significant operating costs?

  Show me one db with auth that can't be maliciously altered. Agree that many usecases would be better served by a centralised system, but many don't seem to grasp how useful an immutable database is. Even with the advent of quantum computing and the havoc that Shor's algorithm will cause, there still won't be enough computing power to undo the Bitcoin blockchain.

    Publication gives similar durability though. (there's no need to do proof of work to track and publish a hash tree)
