Why was interstate commerce difficult to conduct undet the articles of confederation?

Interstate commerce was difficult under the Articles of Confederation due to the lack of a strong central government, which meant that each state could impose its own tariffs and trade regulations. This led to confusion and conflict, as states prioritized their own economic interests over a cohesive national market. Additionally, the Articles did not grant Congress the power to regulate interstate trade, further complicating efforts to facilitate commerce between states. As a result, trade was often hampered by inconsistent laws and practices.
