There needs to be a believeable legal framework behind this.

Imagine a option on your iPhone that says “Enable this to allow geo-location tracking for organisations registered under the NOADSJUSTPUBLICGOOD Act” - then any wifi endpoint could locate you as long based on signal strength etc and that data could only be made available to people registered under the act.

Would we see new understanding of how people move around in cities, would we see better traffic information, Inthink so - as long as people believe that there are real teeth to the laws and they enforced loudly and publically.

We should embrace the benefits of a society wide epidemiology experiment - the benefits for public health are incredible. (Add to that supply chain logistics on open ledgers and many of the new things that just were not possible before and the future of open transparent but well regulated democracies is bright.

Let me know if you spot one.
