That analogy doesn't really work tho. No one is complaining about getting keyless entry (almost all phone had Bluetooth for the past decade or so, no one minded), just the removal of physical keys (the 3.5mm jack). While I'm not an expert on cars, most cars that have keyless entry that I've came across DO come with physical key, either separately, hidden inside the key fob, or the whole key fob works as a physical key as well. The only exception I know of is Tesla, but even they give you 2 keycards and you can purchase more. The reason is basically the same the reason I want headphone jacks back - fobs/Bluetooth can run out of battery, they are expansive to replace so you can't have multiple of them lying around. While I do use the wireless option most of the time. I want the wired option as a backup. Additionally, wired better functionality than the wireless option in this case - FM radio (not relevant for iPhones, but it does for Android), better audio quality, less battery consumption, ability to charge the phone while in use - features I personally am not very attached to but can see why they might be important for other people.
