Your worldview on handicapped accessability has already existed. It was deemed ugly.
But it's not arbitrary, is it? The law says a wheelchair bound handicapped individual has a right to access parking at a public place with a convenient location to an accessable pathway with a ramp. This parking must be as close to the entrance as possible and the parking, path and ramp can't have slope and cross slope such that using a wheelchair is a fight and thus is of no real use. OR, just walking without toe drop is so bad and painful that cracks are real tripping hazards much less stepping up on a curb.
Whether other parking spots are available is immaterial to ramp access distance, slope, cross slope, etc.
One of the biggest obstacles people with mobility disabilities have now is that many in the public have an ugly attitude towards them such as you display in your words here. Whether you actually hold your nose in the air as you cast dissapproving stares as almost crippled folk bravely exit their cars in handicapped spots we can't know. But when I drive to Costco and can't find one HC spot in the many they offer sure tells me we're not just a few.
