A GPS tracker with a cell connection would serve you much better in either scenario. Those are less popular with criminals because they can often be traced back to the purchaser, but they are more reliable and won’t accidentally alert the kidnappers because they tripped an anti-stalking monitor.
Like with the most of technology, uncomfortably. I survived before phones, mobile and the Internet. I survived without AC, Car and so many similar things, personally. Now I prefer them and get real benefit from them.

How would our radio look like if it becomes the norm to put tags from everyone onto everything?
I own a number of them and have attached them to things that are valuable to me, and not just financially. The car is the prime example, but I've also attached one to my dog's harness. He's a rescue Fox Terrier with a prey drive like a missile and no recall skills whatsoever (yet): if he slips his lead somehow we have at least some slight chance of finding where he's run off to. Likewise my waist-mounted hiking bags - if I lose the one that holds my keys or first-aid kit on a long walk I could be in big trouble when I get to my destination. Sadly, the Guardian doesn't mention the positive aspects...
