I had a theory that the way to solve this was a location intelligence data union which sold safely anonymised aggregates and shared the profits, while also litigating on behalf of members under available legislation to stop other people using their data.

Alas, I was stymied by not having any cash to work on it, and the unit economics were not very VC friendly (at least I assume that’s one of the reasons why I didn’t get any traction from VCs).
