Some of us kind of live that way already!
For many years we have bought good food partly for good reusable packaging. One USA boycott we break is a brand of decent peanut butter that has really skookum reusable jars which we keep for midterm food preservation, such as vacuum packing our dehydrated fruits.
One place we shop even packages bulk goods into nice standard jars and charges a deposit. We either reuse the jars at home or stock them with our reusable shopping bags for return on the next shop.
In addition, I am seeing more "refillery" stores, where as you say, it’s BYO containers for cooking oil, soap, dry goods, etc.
