Accessibility is great but its hardly humanity's goal. In most instances your burden is no one else's unless we are talking life or death.
Not only does your comment show ignorance of a significant percentage of humans, it also shows you have zero idea of the fact that good accessibility provides service to everyone.
Have you ever struggled to use your smartphone while driving (temporary blindness, because your eyes are focused on the street),
or pressed the wrong button while sitting in a bumpy, shaking bus, because the button you actually wanted to press was way too small (temporary hand coordination disability)?
Accessibility's best practices also exist for everyone to enjoy a great usability.
