Why is is important that the federal and state governments have separate as well as shared powers

They separated because they were more worried about themselves. They had to compromise to have a strong constitution after the federalists beat the British, also because they thought they would lose their independence. Another reason is they were worried about taxation so they needed to come up with a better plan for the colonists. Hope it helps! Have a beautiful day or night!
