We share it with other people. I, personally, would just ban short people, but they do exist and they love to move the seat away from my sweet spot.

If I had to use the touchscreen to fix it every time, I'd just leave it in a ditch and set it on fire.

My posture is completely different in the city, where I am constantly leaning forward and looking over shoulders to clear blind spots, and my foot is regularly on brake and accelerator. Contrast on the highway, where my head and body are mostly still, and my feet are flat on the floor while using cruise control. Since I'm not moving around as much, I regularly move the seat slightly to reduce pressure points.

Similar with the mirrors: For city driving, I want my mirrors a little lower and narrower to see parking spots while backing. For freeway, a little higher and wider gives better visibility of the blind spots without needing to move around as much. For towing, I want them even lower when backing, and even higher and wider on the freeway to clear blind spots.

Yeah, I might go more than a month without touching either the seats or the mirrors at all. But, I might also be adjusting both a dozen times in a single trip.

I've adjusted mine twice in the last month alone because I needed to fold down the rear seats. But also sometimes you borrow your car to someone who doesn't have a memory setting. Or your car doesn't have memory seats and has multiple users.

If I have to use a touchscreen to adjust my seat once a month, that's 11 times a year too much for me. Buttons? Fine. Levers and wheels like in old cars? Also fine.
