Answer:
The Louisiana Purchase is imperative to the United States since it helped us grow over the mainland. We purchased this enormous land parcel for $15 million and multiplied the size of the US. We got the opportunity to investigate new land and work towards accomplishing Manifest Destiny, the possibility that the US ought to grow over the mainland.
The amount of territory the US currently has would have been completely different if the national government could only legislate based on what is written in the constitution.
A perfect example of this is the power to purchase land/territories from other countries. This was first done by Thomas Jefferson with the Louisiana Purchase of 1803. The US Constitution does not say that the president has the power to buy land from other countries. However, Jefferson said that this power was "implied" by the Constitution.
This idea of an implied power greatly changed the presidency/national government. Several presidents after Jefferson would follow his lead by making deals with countries for territory.
If it wasn't for this concept of implied powers, the US may not have grown to the 50 states we know it as today.
