The first limitation is that the federal government cannot collect taxes, only the states can. The governor would have to ask for the state’s money instead of forcing the colonies to do so or collecting taxes themselves. Before the Revolution, King George collected everyone’s taxes because he wanted the money to run his military and to run his country instead of having other parts of England collect them and have a share of the income.
The second limitation is that the federal government cannot have full control over the states. Each state will be runned by a governor, who will have full power over his/her state. King George had full control over England, which meant that he could have done anything he wanted without anyone stopping him, which is why this limitation was made. So that no one could have full power and couldn’t do whatever they wanted.
