On pure principle I kind of agree, but the reason that the ADA exists is because people with disabilities that require things like ramps and big bathroom stalls with grab bars are not a significant enough market segment to pressure businesses to offer them; the end result of which is that accommodations would not exist otherwise. This is the necessary kind of regulation that shores up a hole that free markets wouldn't solve on their own. Accommodating disabilities isn't profitable.
