Anarchism relies heavily on voluntary cooperation and mutual aid, concepts that require widespread buy-in to function effectively. Without a significant cultural shift towards these values, implementing an anarchist society would face insurmountable challenges. People conditioned to hierarchical structures and state dependence may struggle to adapt, leading to potential chaos and inefficiency. The idealism of anarchism is appealing, but its feasibility is contingent on a collective mindset that isn't yet prevalent.
Specifically, the reliance on community mediation presupposes a level of communal cooperation and mutual trust that isn't universal. In practice, disagreements and conflicts in large, diverse societies often require more robust mechanisms for resolution than those proposed by anarchism.
