IMO the biggest utility of a headphone jack is not for earbuds, it's that it enables you to play music from your phone on basically any device made in the last 30 years. Want to hook up to some random stereo? No problem, you can do it. Want to play music in your car, but you have one of the many cars without Bluetooth? Easy. There's a lot to be said for having a damn near universal audio connector. Bluetooth is nice, but it's not there yet in terms of ubiquity.

My personal use case for the headphone jack is playing music in my car. My car doesn't even have an aux input (I have to use a cassette adapter), let alone Bluetooth. And when I'm on a long drive, being able to play music while charging is a must. I will only very rarely hook up a pair of wired earbuds to my phone, but I absolutely must have a headphone jack.

I'm not claiming that there is no use for Jack. I just think that this is a niche and doesn't require a separate connector in every smartphone. Having a universal connector that can be used for various niche scenarios is IMO enough. We should push for improvements in that regard (e.g. make it easy to charge the phone and use the dongle at the same time).

I wish I had the same problem as you do with your car. Mine is old enough that it doesn't have Bluetooth (I'm not the first owner and Bluetooth was an "extra" in this model) but new enough that there is no cassette player (and no built-in aux input) :)
