Why use blockchain? Why not just have the entity provide a database? Note that the standing may change over time. > Couldn't it even be a one-time use type of thing? I'm not sure what this means. Why use an immutable database for one use?

    > Why use blockchain? Why not just have the entity provide a database? Note that the standing may change over time. The, "Why not use X?" argument seems to be repeated often here. This is a really silly argument if you are using it to discount blockchain. With most technology (nodejs, javascript, email on your phone, holographic video conferencing) there are usually alternative ways to achieve the same thing. When email was added to phones some people said it was silly - their argument was why would anyone want to type emails on their phones when they have laptops already? No one is saying that blockchain is the only possible way to achieve something.
