The binding will make it more likely that crafters will be able to continue to make profit from low level crafting. When an item becomes bound it makes it so that item cannot be sold or traded, decreasing the amount of items in circulation. This makes it necessary for crafters to continue making low level gear. The real competition will be the ease of crafting in the game. Since crafting is so simple and doesn't require farming or hassles with inventory space most people will have multiple crafts at level 10-20 fairly quickly. That is going to be what impacts the low level market the most.
