I think the concept of not owning a coffeemaker and going to a coffee shop daily is both consumerism and minimalism. Why can't it be both?

Wouldn't there be huge efficiency gains (and minimalism) in a coffee shop having one large coffee machine, importing huge bags of coffee instead of tiny packages with loads of waste? Reusing 20 cups for 200 people instead of each person owning 5 cups?

3rd world countries have coffee shops btw...
