It's because phones are not single devices these days they're a (restricted) general purpose computer, that fits into your pocket, and does not use physical input devices. The software is geared towards it being this way rather than it being a communications device where you use for calls and text messages. It doesn't help that the user interface changes every year or two so every time there's an "upgrade" you get confused and need to re-learn how it should be used. Or that on every update there's a slew or dark patterns designed to cost you money or privacy, or both. (This applies to computer operating systems as well which further reinforces the fact that a phone is a computer and not a dedicated device.) It's also unfortunate that you cannot ever decide to stop using a mobile phone, as many essential services like banking and government require you to have one. So you're stuck using one for the rest of your life wether you like it or not.
