I actually can kind of understand a wheel chair ramp. You will never need it if you don't have one, because nobody with a wheel chair will ever come. I can't imagine how frustrating it must be to be in a wheelchair and kept out of so many places.
The rest? Most of it sounds like a combination of people wanting to believe nothing bad can ever happen to them and the nanny state wanting to keep itself employed.
As the new mother of a 3 month old, I'm really getting a taste of how much it must suck to be in a wheelchair. The stroller can't go into half the places I try to visit. Even the bank wasn't wheelchair accessible. And in many stores, even if they are on the ground floor, the aisles are too narrow to navigate.
