You have an identity entity off-chain (say a government body) that you get some kind of cryptographically signed piece of information that doesn't relay any of your personal information on-chain but allows entities on-chain to know that you are in good standing with the off-chain identity service? Couldn't it even be a one-time use type of thing?
Why use blockchain? Why not just have the entity provide a database? Note that the standing may change over time.

I'm not sure what this means. Why use an immutable database for one use?
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.
7 banks and 4 telecom companies are nodes on the network. They provide the identity details of a person.
Very interesting use case. Take a look
