The argument is that selling something that nobody wants to the government is not entrepreneurship. This, I concur. However, it was wrong to conflate something which the author couldn't think of anybody wanting with something that nobody wants. Secondly, the entrepreneur isn't "selling" to the city. The city is getting money for free, i.e. cut of the proceeds without having to come up with capital or operating expenditure. The lack of car parking spaces in cities is a growing problem and cities are actively trying to solve the problem of public access without having to fund public transport, since hiring public service workers may not be an option. Providing bikes for hire can be seen as one of the measures a city can use to reduce cab traffic. For me, once I find a car park, I am very reluctant to leave it until work finishes. If I have to go anywhere else say during lunch time, having access to a bike would be extremely handy.
