What do you do when, say, the TSA, or the police, or some equivalent thereof steals it, as was discussed in another thread?

I take it you also don't use any online service, because 99% of them don't take cash? Don't own a cellphone, because that broadcasts your location data 24/7? Don't own any device that actively scans for wi-fi networks?

Your government already has fingers in all of those data sources.

When the police steal my cash, I'll take that hit (it has never happened yet). I do not have a cellphone nor does my laptop scan for WiFi networks. I do need to get that cash, so I do go to cash machines to get it from my account. Those machines are generally close to where I live, but I guess the state already has my address, so not much new is revealed there (my location near where I live a couple of times a week).

I do buy a few things (books, DVDs) online, and pay with a card -- that reveals my address to that business, but that would be the same if I sent cash (or a cheque), they do need an address to which to deliver. As I say, I assume the state has my address, but there's no need to give them my location when I'm not there (nor to tell them when it is I'm not there).

So returning to your assertions:

"we already track ourselves by virtue of using credit cards at every business we visit"

speak for yourself, I pay with cash

"The three major credit rating agencies already have complete knowledge of every place I visit, and every single thing I buy"

That's your choice, they have no idea where I go, nor what I buy except that I'm rather keen on French novels and 1960s Italian films. Mind you, since I'm in the UK those suspicious activities might land me in trouble with the Brexit police [looks nervously out of the window].

What's the problem for web store to take cash? Delivery person can take it.
