It should be obvious but, limitations, whether they be related to time, budget, or other resources, make stock assets desirable.

For instance, commissioning a custom icon set rather than picking one off-the-shelf is a luxury only some projects will have access to.

Additionally, oftentimes stock assets function as good placeholders until a larger budget comes into play. Suppose you are working on a video game and waiting for environmental assets to be complete; in the meantime, a sample texture may do.

In a perfect world, perhaps every font, icon, illustration, photo, or texture would be bespoke to its exact application. In the mean time, we have stock assets.
