What is the downside of a federal system?

One downside of a federal system is the potential for duplication of government services and regulatory frameworks, which can lead to inefficiencies and increased costs. Additionally, conflicts may arise between state and Federal Laws, creating legal ambiguities and inconsistencies. This division of power can also result in unequal access to resources and services, as some states may be better equipped than others. Furthermore, it may hinder swift decision-making in times of crisis due to the need for coordination among multiple levels of government.
