A 10-Year Battery for AirTag

I know this is useful (for something), but I'm stuck on the plot holes in the motivating story...

Why didn't they replace the battery when the app complained?

How long would a thief really keep the AirTag anyway?

If the thief did keep the AirTag and you tracked them down, then what? A confrontation has a fairly high chance to have a worse result than losing some equipment. You could try to get the police to do it, but that's going to take more time, during which the thief is even more likely to ditch the AirTag.

Anyway, you're really swimming upstream trying to think of aigtags as an antitheft device. They're really for something lost, not stolen. Generally, they are specifically designed to not work well in adversarial situations.

There exists a small percentage of men who will go absolutely savage on somebody for stealing from them, and the existence of those people is probably a bigger crime deterrent than the police.

So I say, shine on you crazy air tag tracking vigilante diamonds.

I don't want someone to put razor wire on their catalytic converters so that it slices thieves' fingers off. I do, however, wish to leave the impression with thieves that perhaps my catalytic converter is protected by insanity armor.

Razor wire is called that because it looks like a razor.

The danger is about the pointy shape.

I'd be careful climbing it, if you fall/slip it's way worse than barbed wire. (Not sure how to do it tactically)

I don't think it's that unethical to put it around the cat if it's obvious. It might be a danger in an accident or something.
