there are many, many reasons for this. For a definitive answer, you should read the constitution and the federalist papers. Simply put, the federal government is responsible for acting in the interests of all states in the union, protecting international borders, aiding states in the cases of disaster (natural, economic, etc) and some other very broad aspects (a unified currency, a unified trade, standards of education, health care standards, etc). Many states might have different goals than some others, and that is fine, but reaching those goals cannot impede on the well-being of another state, so there must be a unifying standard. Also, on a global stage, we are much more powerful together than any one state would be on its own, etc etc etc. The more i go on, the more complicated the role of the federal government becomes, so I'll point you back to my first statements, look to the constitution and the federalist papers for the real answer.
