Can someone please tell me why we need this?

It’s a touch-less soap dispenser.  My girls are convinced we need one.  Because the soap dispenser is germ-y.  But you’re going to wash your hands…. I respond.  Yeah, but the pump in the bathroom gets so dirty from everyone’s hands, they chirp.  But you’re going to wash your hands, I respond again.  And this is in our bathroom.  In our home.  We all share germs as it is.  What does it matter if the soap dispenser has germs on it.  The soap dispenser that you are using to dispense soap into the hands that you are going to proceed to wash said soap (and germs) off of.

Does anyone else see how silly this product is?  Or is it just me?
