Somewhat off-topic but yeah, I can understand your frustration... And it would naturally be great if airlines would be able to accommodate for people not fitting into average parameters. But it's also a tricky proposition, as you surely understand. Should obese people get huge, two person sized seats? Should people with stiff joints automatically get extra legroom? Should people with a cold have no passengers in a 2 meter radius around them? How do the airlines check/verify these things (yes, height is obv easy)?

Besides, even having the option to pay for extra legroom is what I'm missing altogether from the mobile phone market. Do you see my point? At least you have the option when it comes to legroom. I don't have any sub 5" options when it comes to Android phones, even though I would be prepared to pay extra for it.

Ok, but then look at airline prices. Prices have dropped fairly consistently over the last 30 years. Even though you have to pay more, you are still paying less than people over the years. Seems fair to me.
