The country does't have a name because at the time of it's creation all of the states were individual colonies, each with their own name, virginia, mass, new york, etc. Each colony had it's own government and customs, and as is still present today, dialect. When the colonies became independent from england, they chose a loose alliance of sovreign states, known as confederation. As such it was not one country under one government, but several equal states agreeing to defend and trade with one another, and allow open passage from state to state for citizens. Essentially, however each state was it's own country, and so wouldn't have any business in changing it's name, a sign of the fierce individualism upon which the country was founded. This is the same reason our capitol is not in a state, but it's own district, because allowing any one state to have the capital of our country would elevate that state to the most important instead of one among equals. I don't think it was particularly stupid at all.
