I get that pizza at home is a whole hobby, yes. And if you don't want to do it, it's all of those things that you say.

1) My pizza oven runs on gas not electricity. Not that this is better environmentally. Some run on wood.

2) I'm getting better results than I can get in a local pizza place. Cheap pizza is not great pizza. Home pizza making has a learning curve, it's more of a niche thing than e.g. cooking a steak or burger.

For grandparent post, Pizza is of course not a "dessert", it's a savoury main course. Full of white flour, cheese fats, and salt. So also not health food.
