Many people enjoy popping bubble wrap. Not one of them ever said, "Ya know what would be nice? A bubble wrap popper built into a belt buckle." And yet somebody did indeed invent the Burst Your Bubble belt buckle.
The therapeutic value of popping bubble wrap comes from squishing those mini air pillows between your fingers. The tactile and auditory sensations that result trigger a neural response in the brain that is not unlike taking a drug or seeing a guy in a Porsche getting a speeding ticket.
