I really do not know why a blockchain is necessary. If people have ownership over their own data, all that is really needed is a place to store it and some kind OAuth scheme to access and manage it. I mean, sure, smart contracts on a blockchain could do that, but so could hundreds of other architectures.

It's not a matter of what's possible but rather a matter of who has control and access to that data. Do you want a decentralized platform or Apple to protect your records. Fwiw I'm not advocating one way or the other.

Agreed -- I don't think blockchain introduces anything _entirely_ new to any type of application. Blockchain in healthcare goes a lot further than user control/convenience though, and a "holy grail" success would mean complete interoperability across the industry in terms of security and data & knowledge sharing. Also the whole "centralization" bit was already mentioned.
