Physical scenarios, universal business exchange - just like exchanging pizza back then, using equivalent material consensus value to swap, everything flows naturally. After all, people earn money and accumulate wealth to ensure food, clothing, shelter, and transportation without worry. In this intelligent era, with homogeneous centralized procurement and homogeneous distribution, if there's no consensus, it wouldn't appear under the same sky. Achieving internal circulation, you can use exchange to solve real practical material needs. On top of spiritual civilization and morality, consciously and voluntarily exchange gifted gratitude feedback, adding an extra dimension to life, bringing warmth together through consensus, co-construction, and co-sharing to provide mutual material life security. No matter what we're engaged in, it's ultimately for ensuring food security and elderly care. Welcome to discuss.
