In practice, it is inevitable that there should be people who control the important means of communication and that they should assume certain standards in exercising such control. The extreme case of ‘free speech’ would seem to be a set of arrangements in which anybody can communicate anything at any time to any audience he chooses. This is not conceivable in a society of any size or complexity. Attempting to reach this condition could only lead to the population being forced to listen to the dreary rantings of thousands of humanist poets who would quickly emerge once the constraints of supply and demand had been removed.
