This is the tradeoff of any regulation or law. Whether it's ADA compliance, minimum wage, environmental regulation, or even just ordinary property rights, there is always some break-even business somewhere that cannot afford $1 in incremental cost to trim the tree growing over the property line (or whatever). There's no free lunch anymore, we are out of pareto improvements. Of course ADA enforcement will cause some coffee shop somewhere to close. That in itself doesn't tell you very much. You need a fuller cost benefit analysis to tell you if the ADA is good legislation or not.
