As for crime prevention, I think you’re overestimating how much of a benefit that would have. Stolen device protections remove the value from the stolen device. That’s not the case for your stolen bike - thieves don’t actually care if you can track the device because a) knowing where your stolen property is doesn’t actually aide in it getting recovered b) as long as they can move the stolen product along quickly enough the information becomes too stale to action on it (remember - police usually need a search warrant). My cousin’s car got stolen with AirTags in it but he got lucky in that the police did something about it - plenty of news stories of AirTags in cars with people trying to get the police to do something and the police not being able to for a variety of reasons. And that’s cars which are orders of magnitude more expensive than bikes that police won’t bother with. Look up VanMoof theft stories to convince yourself that tracking is useless: https://www.reddit.com/r/vanmoofbicycle/comments/zbexyr/upda...
There are also dedicated devices, such as this one - https://www.t-mobile.com/devices/iot/syncup-gps-tracker-devi... - and lots of companies in China make similar products.
There is a genuine need for anti-theft technology. Apple doesn't have to address that market, likely because they're afraid of brand damage, but stalkers already have plenty of options available.
It’s not just brand damage - passive tracking using every single smartphone opted into the tracking vs active tracking where you have to expend more battery AND pay for an ongoing cellular connection each month is a tangibly different use-case with different threat models.
This math doesn't make sense to me.
You can argue that you'd be more dilligent about recharging but I'd counter that at scale you'd be the outlier. On average I'd actually expect an average battery life when stolen closer to 0 because people wouldn't be diligently recharging them & reattaching them (i.e. either the battery life would be 0 or the device wouldn't be attached to the desired property).
A 14-day battery life would then mean an average of 10.5 days of protection, which isn't too bad.

I don't know about this. For bicycle users, charging their rechargeable headlights and taillights regularly (typically once weekly) is very much a habit already. This is just another thing to charge at the same time, which is a time they aren't riding their bicycle.
I understand the personal safety issues. They're important. I get it. That doesn't stop part of me from wishing I could use these cheap, convenient lost item devices to help me track down stuff that wasn't exactly accidentally lost.
