| How exactly would you do this? > in an encrypted manner that has guarantees in place that only valid criminal investigations can decrypt What constitutes a valid criminal investigation, who decides? Do you, does a prosecutor, a judge, the police? Is it a valid to decrypt your data just see if you were at a specific location at a specific time? What about so the police can check a theory? How about to see if you joined an unsanctioned protest, smoked a joint, speed while driving, downloaded a movie? Speeding and copyright theft are both criminal, are you saying that your happy to make it trivial to investigate you for these crimes an prosecute you for them? It used to be criminal to engage in homosexual behaviour, and in some parts of the world. Once upon a time that would be a valid criminal investigation in the US. For a short while it was looking like abortions might become criminal in the not too distant future.

Some sort of formal process with reasonable oversight the necessity of multiple points of compromise and/or collusion in order for the data to be abused for non-governmental use. Bottom line, I can't say I've "solved" the problem and have the perfect answer to your question. But I'm sure we, collectively as a society filled with smart people that want to move us forward, could put down some (fundamental?) tools/rules/processes that would negate the potential for abuse up until a certain point. Maybe we can't do 100%, but we could do 95 or 98%?

Yes, very much so Yes! Especially the location based stuff as it's perfect for investigations without revealing details. "List all people that were within 50m of this crime location during this timespan." <-- that is so unbelievably powerful as a crime-solving tool, that I am baffled that we're avoiding it out of privacy concerns. As for the speeding example: That's probably another example of us already giving the data (car's black-box) to government (and private insurance companies) in order to facilitate an investigation.
But to your point about drug-use, speeding and copyright infringement. If we don't want something prosecuted then we shouldn't have it as a crime. But as it stands now, a bunch of what you mentioned is a crime. That represents an implicit agreement by all of us in society that says we deem those things punishable. We can't hide behind lack of capability to police said crimes, but still label them as such. That is ripe for offical-power abuse. For all we know, if we lived in a society where we had such strict enforcement of laws as I suggest, we'd potentially have greater churn and change in our laws to match the opinions of society as it changed and evolved.
> "Privacy is a fundamental tool for allowing society to progress and change, and for avoiding totalitarianism."
I disagree. I'm not seeing it. There is just way too much going wrong today in 1-st world countries whilst we have really good privacy for it to be the case. We're downright descending into totalitarianism and thought/opinion control territory, all whilst our "privacy" is mostly maintained and respected. Are you saying we need more of it? What would that look like to you?
