Does anyone really need an apple cozy?

I crochet as a hobby. I google image things like "crochet patterns" to get ideas. I came across the most insane thing I've ever seen. An apple cozy. Just google that to see what I mean. There are also pear and banana cozies. These are crocheted or knitted pouches that fit perfectly around the fruit. I read the blog of someone who designs these, and they claimed that these prevent fruit related mishaps. I can't think of how these things can be seriously useful. It's driving me crazy. I put an apple in my purse everyday for lunch. No problems yet. I'd like to hear from people who think this is a useful item.
