I love the approach that some perspectives consider this a problem waiting for a solution so we should at least try to be inventive and consider possibilities.

I love the approach that some perspectives consider this a problem waiting for a solution so we should at least try to be inventive and consider possibilities. The problem is everything about this is contingent upon perspective and there are too many to have a solution that captures all concerns. When your category is "Every Person In The World", or the not-so-tiny pool that is "Apple Customers", the only solution that fits all would be one that empowers the individual because it shifts off the burden of competing perspectives. The problem is compounded by the fact a golden key scenario only works with the current web services model we've become dependent upon. What happens when encryption is the default everywhere all the time and computation is performed by blind services or smart contracts mapped together over a trustless network a la bitcoin style? Everything about the experience could feel the same with the exception being control over your data is shifted from a third party to you. One possible solution would be to establish computational governance. At least at that point you have a communal opt-in which gets you away from the problem of perspective. In the same way all motorists agree to a set of rules for a given area, you could be given access to use services if you agree to a set of policies. One such policy would be to have access to your data shared to a third party if a reasonable process is followed (a dumb example would be if a majority of your peers agree that you should be investigated). Probably another can of worms but at least then we're operating from a workable premise.
