Do you give much thought to the interplay of intended use/wear and appropriate yarn? It is a simple question that is worthy of entire tomes to fully explore the issue. Indeed, many a writer has tackled what to use when, many a blog post has offered an opinion and a multitude of chat posts have ranted about why something can't be used as proposed.
Will a cotton skirt sag where you don't want your saggy bits to be emphasized?
Will alpaca be too hot for an airy summer tank?
Will baby develop a rash if the blankie has a mere 25% wool?
Will a yarn prone to pilling create a mess on the under arm area?
Ad infinitum. . . . .

That's right, I'll take my coffee black and my functionality with Sugar 'n Cream.
