Try not paying the rent on a storage unit. After a month or so, you'll find a new lock on the door. Go long enough without settling up (read the lease), and they will sell off the contents.
Sure, and skipping too many car payments gets your car repossessed, skipping too many mortgage payments leads to foreclosure, etc....
Those are serious consequences, but they're localized to the specific thing or service at issue. You don't lose access to your car because you fail to pay rent on your storage unit. Your house doesn't get foreclosed because your car gets repossessed.
But they can't lock you out of your house, or sell off the contents of your house that were at one point in your storage unit, just because you stopped paying the rent for your storage unit.
