Contrast Family Video (privately held and still going strong) vs. Blockbuster Video (no longer a thing). Sure, video rental may not have enough money in it to satisfy the Wall Street vampires, but there's still enough life in it to make money. If you don't have to keep vampires happy, you can invest your profits into your business, or even into new ventures.
Hilariously, there's a Family Video in my neck of the woods that moved across the street into the former Blockbuster location. They retained ownership of their original building* and are using that for a new business venture (a 24-hour fitness center). EDIT: In their new location, and many others, they have a Marco's Pizza attached.
* There's another whole issue: owning your real estate rather than being beholden to a landlord.
