I don't understand why some people are so against AirTags. Don't use them if you don't like them, but for those of us who find them useful, they are a great tool at a low price.
The user discussions about AirTags on apple.com suggest the big consumer issues are: ignorance (failure to read the most basic instructions), unrealistic expectations (promoted by Apple and socials), and incorrect usage, all of which can quickly lead to disappointment and resentment.
If you got some AirTags for xmas, watch some video clips, read Apple's instructions, and, once you get them paired to your phone, practice using the FindMy software. Ask your kids to stash your keys in the yard and see if you can locate them. Then try a more challenging search at a school playgroud or park. There are AirTag games and silliness that appeal to the adventurous:
I like ours; they've helped both of us locate our keys more than once. I do wish they produced a warbling tone that was louder. I think they are particularly difficult to locate in 3d space when beeping. For this spring's trip to Spain with RS, I plan to put one in my carryon bag so I know it's on the bus.
