Limited government is important because this would preserve the individual liberties, certain rights and freedom. This also protects private property and enables the people to have control over their own lives.
Representative government is very significant because the individual citizens are given empowerment to exercise their political rights. All the people are fairly treated to have the voting rights on who to elect.
Separation of power is very important to have control in the government. History proves that if the power to control the people rests in one hand, in most cases, they would be abusing this power and others would be oppressed. The separation of power is established to prevent the abuse of power and protect freedom for all.
