What is one reason that the union strategy for defeating the south included a naval blocked of southern block?

One key reason for the Union's strategy of implementing a naval blockade of the South was to cripple the Confederate economy by cutting off access to international trade and essential supplies. This blockade aimed to prevent the South from exporting cotton, which was crucial for funding their war efforts, while simultaneously restricting their ability to import weapons, food, and other necessary resources. By diminishing the South's economic capabilities, the Union sought to weaken their resolve and ability to sustain the war.
