First of all, store-bought tortillas are not fresh, and nothing beats fresh homemade food. Also, the fact that store-bought tortillas are made a few months in advance. So, consider the preservatives needed to keep them fresh for that shelf life mentioned on the package. Also, store-bought is soft, but that's because it usually has a lot of lard or palm oil. However, they still taste chewy and most people believe it's natural. Nope!!
