Yeah I agree. I mostly get a straw for ice tea, which comes in styrofoam... Styrofoam is unfortunate. It is super easy to recycle, but too inefficient to transport. I've been trying to come up with a solar powered Styrofoam recycler that stores up blocks of solid polystyrene for pickup. The hard part is knowing people will put other things in to mess it up. Otherwise a tank of gasoline to dissolve it with a closed evaporation loop is all you would need.

Most common reason to use a straw is when drinking from a vessel that's full of ice.

It's funny how luxurious a simple ice-filled straw-included one-time-use styrofoam cup of Coke from the McDonald's drive-thru is, really, and how much we take it for granted.
