> Imagine instead if the government simply gave disabled a stipend to help fund their transportation costs. A diverse market would emerge. Some businesses, eager to tap into the fountain of government stipends, would charge higher prices and offer wheelchair friendly vehicles.

Even better would be to make it cash instead of a stipend. Then you don't need a bureaucracy just to verify that the money is being spent on a particular thing, and if it turns out that the recipients prefer to use the money for something else instead, that only increases efficiency. People can choose the more efficient alternative between paying a premium for wheelchair-accessible transport or just having products delivered via UPS.

Or simplify things even further and just have a universal basic income to replace this sort of thing as well as the other thousands of other individual subsidies that end up producing mountains of unnecessary paperwork when we could just give everyone one unconditionally.
