Mass surveillance isn't necessarily bad. It depends how it's implemented. The solution you describe is basically how it works with the intelligence agencies, in that only a miniscule fraction of the data collected in bulk ever reaches human eyes. The rest ends up being discarded after the retention period.
In terms of outcomes, almost nobody is actually surveilled, as the overall effect is the same as no data having been collected on them in the first place.
That said, I am personally more comfortable with my country's intelligence agencies hoovering up all my online activity than I am with the likes of Apple. The former is much more accountable than the latter.
If your ex-spouse was a contractor for a government agency with access to the mass surveillance machine, would you still feel comfortable "that only a miniscule fraction of the data collected in bulk ever reaches human eyes?"
What if you were a candidate for political office, pushing opinions that angered large swaths of the Intelligence Comminity?
The "minuscule fraction" of content is not surfaced by some random roll of the dice - it's the definitionally most interesting content, in the sense that some human went specifically looking for it in the heap of content caught in the dragnet. And it only needs to be interesting to at least one person with the clearance to search for it.
Maybe that means it's a video of a child being abused, and some morally upstanding federal officer is searching for it because anyone possessing it is ethically and legally culpable for the abuse of that child... Or maybe it's a PDF containing evidence of FBI kidnapping and torturing innocent civilians, and some morally corrupt federal officer is searching for it because anyone possessing it is a liability who needs to be silenced... Or maybe it's a JSON file containing the GPS locations of an individual for the past year, and some emotionally scorned federal contractor is searching for it because that individual is their ex-spouse who's moved onto a new partner.
Are you really prepared to put your faith in the trustworthiness and moral clarity of the population of 100k+ people with federal security clearances?
What leads you to believe that access to search these datasets is some sort of unregulated, unmonitored free-for-all for anyone allowed to wander into an intelligence agency building?
The scenarios you invented sound very far-fetched to me, if these did happen I very much doubt the perpetrator would be able to get away with it.
> At least a dozen U.S. National Security Agency employees have been caught using secret government surveillance tools to spy on the emails or phone calls of their current or former spouses and lovers in the past decade, according to the intelligence agency’s internal watchdog.
