This is such a quintessentially American thing, I've never seen one in real life. Are pizza boxes in the states especially thin so that these are necessary?
I think the concern is more about stacking multiple boxes and the combined weight of everything pushing down on the bottom box. 2-3 pizzas is probably fine without, but when you get a large order for a party or school or event with 5 stacks of ten pizzas each the weight becomes a problem.

Shopping bags used to be free but they started charging for them and slowly people adapted to buying more robust reusable bags. Great to no longer see bags flying about in the streets.
Plastic straws are gone. Plastic cutlery is gone. Both are made from paper in McDonald's.
There's been good movement to reduce plastics. That said there is still a tonne used. My recycling bag at home has so much plastic in it. There really needs more to be done.
