What were four reasons that Eastern luxuries were expensive?

Eastern luxuries were expensive due to several key factors: first, the long and arduous trade routes, such as the Silk Road, increased transportation costs. Second, the rarity and high demand for these goods, including silk, spices, and precious metals, drove prices up. Third, the labor-intensive production methods, particularly for textiles and artisanal crafts, added to their expense. Lastly, the monopolistic practices of certain traders and middlemen further inflated costs by controlling supply and distribution.
