I think the fact that the Articles of Confederation were replaced by the Constitution less than ten years after ratification is a good indication this type of government would not succeed.
There were four major weaknesses of the new government, and three of the four affected the day-to-day running of the new US government.
First, the Articles did not allow the Federal government to raise taxes, so there was no way we could pay back our $4 million war debt. This meant our economy was shaky from the start, with no means to establish itself internationally, or borrow more money when needed.
Second, there was no provision for a national army, so defending the border against native attacks, the northern frontier against British incursions, or our trade ships at sea was impossible. All we could rely on in an emergency was state militias, and the states did not have to help each other or the national government.
Lastly, it took a 9/13 vote in Congress in order to pass national laws, which was difficult at best, and rare as it turns out. So as the need arose for national legislation, it was difficult to pass anything.
