Katz v. United States is an interesting case if you're interested (tldr one thing the case implied is that if your actions are freely observable by others of the public there's no expectation of privacy).
personally I think the only option these days is to push for very short retention policies governed by law such that use of information is inadmissible in a criminal situation (e.g. say a 1 week retention, they can't go scrubbing footage from months back to convict, wouldn't be allowed during discovery), and making it harder or illegal to share with other non-government entities. stopping collection I think is a ship that's sailed imo. it's pretty unlikely public or private surveillance (for supermarket like stores) will ever be made illegal. in fact I can't think of a country where it is.
- as a side note, suggesting to switch to Whole Foods is hilarious. Whole Foods is owned by Amazon, and you can look for yourself all the tracking they do
