In no other domain is implicit, cross-arena tracking by default acceptable. Computers _should be_ no exception.
Maybe you don't think it should be acceptable, but it's the norm everywhere. Computers aren't an exception.
Your purchases are tracked by credit card companies. Your license plate is tracked by road cameras. Your financial history is tracked by credit bureaus. Your phone calls are tracked by your telephony provider.
And you haven't opted into any of them.
In fact, except for the annoying cookie pop-ups on websites, I've never encountered opt-in tracking anywhere in my life. Everything is tracking-by-default, and you're lucky if you get an option to opt out anywhere.
Most of the tracking you mentioned is done for purely functional purposes (the product/service can't work without knowing who you are, etc) where as the majority of online tracking is purely there for wasting people's time with ads.
What's a domain analogous to computers without tracking? I suppose all those are "by computers" at the end of the day, but I can't think of anything I do that isn't tracked somehow.
