What are the demerits of inner line regulation?

Inner line regulation can lead to inefficiencies in resource allocation, as it may restrict the movement of goods and people, hindering economic development in border regions. It can also foster a sense of isolation and resentment among local populations, as they may feel marginalized by central authorities. Additionally, the administrative burden of enforcing these regulations can strain government resources and create bureaucratic obstacles. Lastly, it may unintentionally encourage illegal activities as individuals seek to circumvent restrictions.
