I too see many usecases for the capabilities you describe. I don't see how Blockchain solves it better than "regular" solutions though. Can you give me a concrete example where such data control is best implemented with a Blockchain?
Every single concrete example I can think of personally would work better with a normal database and some kind of Auth scheme which does not involve Blockchain, but maybe I'm just thinking of the wrong usecases?
