I'm one, and the SO is a Zillennial; neither of us own irons. Just don't see the point. Dryers are fairly effective wrinkle removers, and any remaining creases will eventually come out simply by wearing the clothing.
Regardless, delicates get air dried. I live in a "right to dry" state (i.e. it's illegal to ban clotheslines here), but even if I didn't, you can always hang them over the shower rod.
I iron for the creases!! I understand why many people wouldn't have use for them but I like having crisp collars on button downs and polos and a slight crease to certain khakis
