Why do enantiomers have the same properties in an isolated system

I would really love to know the conceptual explanation. It's bothering me.

Try to think of enantiomers as your left & right hand. They can do all the same things (open, close, wiggle fingers, make fist, wave, point, etc.) Enantiomers can do all the same "things" also, like H-bond, boil at a specific temp, etc.

Your hands differ in their ability to fit into a glove, and enantiomers differ in their ability to fit into a biological system. Their left- or right-handedness only matters when they are being fit into some kind of biological "slot".
