I will give you a few of them
1. No regulation or trade regulation means control by the way so they would fight for what they want
2. There was no court system so if you are accused of something, you would go straight to jail
3. Required votes from all of the 13 states to change the articles so nothing would be changed
4. No power to enforce laws. So everyone will do whatever they want and not follow the law
5. Government could not tax so no taxes= no money to run the country
Hope this was helpful
