What's the benefit of fielding an onside kick if you're on the receiving team?

So in order for the kicking team to get possession of the ball, the receiving team must touch it first. Why would the receiving team put a returner in place to field the onside kick? If nobody is there to field it from the receiving team, they get it wherever it stops. It seems smarter to put all your punt returners far away from where the ball will be kicked, like in your endzone for an onside kick, so it automatically fails.
