Chad would have actively promoted that you add stuff to his garage. He'd have also encouraged you to encourage others to put their stuff there -- and he'd have encouraged you to put stuff there on others' behalf.
Plus, somehow, convincing people to put stuff in his garage (greatly, greatly) increases the value of the garage.
So yeah... I know it's a joke, but it's a labored one.
That would be true if Chad were running a storage service, which he isn't!
