You could make that same argument for health and safety regulations. Why have them? The market will compensate the least safe places higher. But still I would rather know my workplace has some sort of minimum safety standard rather than try to guess and find the one least likely to get me injured/killed. There are at least 2 market failures I see. One is perfect information. The average worker will not know enough about how after hours access request system is implemented before starting. The other is perfect competition. In an ideal market there would be more competition that would give the worker enough choice to work without this after hours request demand. But in the real world the employee often does not have this choice.
