You don't seem to understand what the previous poster said: all of this can be achieved with a database that allows some open access. You don't need a consensus protocol on a distributed system.
I'm absolutely aware that there are other possible solutions, although I doubt any of them are as practical as a smart contract blockchain solution.
Given that you seem to think that it's not that hard, I wonder if we have a different understanding of the requirements here.
We're trying to make the payment process more transparent and verifiable as a way of increasing trust. You say that we can do that with a database that allows some open access. I don't really see how.
For example - who runs that database? If it's the company that offers the insurance, it's a nonstarter - it doesn't help with trust. If it's some third party, then it's precisely as useful as the trust the customer has in that third-party. Such an approach could work, but in my opinion brings with it more difficulties than a blockchain solution in most cases.
Even if we do find someone trusted to run the 'database with some open access', there's still the question of being confident that payments are made according to the data in the database, and that the data in the database is updated according to the appropriate rules.

Don't oracles have the same issue?
