This is a great topic that we should need to consider sometimes because the world now is heading to much highly digitalization. And as part of being digitalized, I think that fiat or physical money will be out of the way. Maybe if this will happen, bitcoin supply will be unlimited in order to cater the demands of the people across the globe. Have you ever imagined as well that the "Suggested Retail Price" of our essential needs will be a bit higher or unstable each day? Well, I just feel it would probably goes like that since we all know that bitcoin is volatile by nature so the prices of goods will be unstable for sure depending on the market movement and the supply itself. Its really hard to make an imaginary scenario in purchasing life's necessities without fiat. However, if it will ever happen in the future, things will be slowly implemented in a gradual way.
