I suspect a frozen pizza factory machine is too large and sophisticated for this market. You can't fit it into a McDonalds-sized space.
The actual ingredients may be more fresh than if a random pizza joint bought them from a grocery store that picked them too early, shipped them half way across the planet, let them ripen in the back, brought them out, got bought a day later, left them hanging around for 5 days at the pizza store fridge before cutting them and putting them on your pizza 8 hours later.
Yes, good quality toppings are necessary.
But what really sets pizzas apart is the crust. You _must_ have a good quality crust.
Unfortunately... it's the crust that most cheap and/or frozen pizzas skimp on.
