Why was federation a bad idea?

Federation can be considered a bad idea for several reasons, including the potential for increased bureaucracy and complexity in governance, which may lead to inefficiencies and slower decision-making processes. Additionally, it can exacerbate regional disparities, as smaller or less powerful regions may feel marginalized or underrepresented. Moreover, the pooling of sovereignty might lead to conflicts over national identity and cultural differences, undermining local autonomy and cohesion.
