the dollar store will be rebranded into the 2 sat store

hahaha good question but quite hard to say. I think in a bitcoin world (no fiat anymore) all goods/services prices will be driven by pure free market, demand and offer.

So if you want to sell me your apple for 1 sat, I will analyze first my effort to obtain that 1 sat that can compensate your apple energy that is giving me back.

Remember Bitcoin is pure energy stored in a perfect way, as money, so we can exchange it easily for goods and services. So when you will buy something with your sats you must calculate in some way, how much energy you receive back. Energy is not "consumed" it just change its form.

a coffee?
