Brick and Mortar Bookstore Owner: Bookstores are the backbone of our country. Democracies depend on a literate population, and reading fosters the creativity necessary to drive innovation. Brick and mortar bookstores introduce people to new books and entice people to expand their literary preferences. Without brick and mortar bookstores, the demand for books would collapse, killing the publishing industry. Digital Bookstore Owner: There is no denying the importance of reading for any democracy. However, digital books are the future. People can easily access our enormous catalogue of books, which is far greater than any brick and mortar bookstore. We provide synopses and reviews that allow people to discover new interests. In addition, digital books are cheaper than paper books. What is the main point of dispute in the two arguments? ['Customers prefer paper books.', 'Digital bookstores depend on the existence of brick and mortar bookstores.', 'Digital books are cheaper than paper books.', 'Digital books will someday replace paper books altogether.']
