The theory of the ADA is that rather than just enforce everything via bureaucracy, we'd give individuals the right of private action to push for the accommodations they need. Then we get a hopefully-good level of accommodation without a lot of the kind of waste that goes with central planning.

But if somebody is going to use the legal system to make a lot of money by generating spurious complaints for every business in an area, then that's not the right mechanism. If every business should be immediately compliant, we should just make it part of the building code and/or part of the business licensing process.
