Why is the Elastic Clause essential to American Democracy?

The Elastic Clause is extremely necessary because it allows all new things introduced that we're not specifically addressed in the Constitution to be properly governed. As stated before, Hamilton used the Elastic Clause to create the National Bank because it was necessary to carry out the borrowing of funds and taxing citizens, but the Elastic Clause could also be used to justify criminal laws as well. For example, the Federal Kidnapping Act allows federal authorities to pursue a criminal if they have taken their victim over state borders, because local law enforcement wouldn't be able to. 

What would happen to American society without the Elastic Clause?

The Elastic Clause plays a large role in peoples lives. Without it, many things would go ungoverned. This would inevitably cause people or authorities to argue over how or who should govern certain aspects of society, and this leads to further division of the people. Being the United States of America, it is important that we all work as a single unit for the better of the nation, which means as little division as possible.

How is the Elastic Clause related to other essential principles?

One government principle that the Elastic Clause is related to is the system of Checks and Balances. This is because Checks and Balances involves the even power distributed within the government branches, and the Elastic Clause ensures power given to Congress and allows them the right to create laws that are required for the government to run smoothly.
