Is it accurate to say that business can be created? Since the pool of money a society has is fixed, businesses are only competing each other for market share. If population grows and the pool of money is fixed, on average everyone will become poorer. Then, as a whole, how can an economy be sustainable? Is it implied that the population must saturate? What would happen if, instead of collecting taxes based on transactions, the government collects taxes based on saving? For example, what happens if the law is that "For every dollar you earn today, you have exactly 1 year to spend it. If you don't spend it by then, that dollar belongs to the government. Pure transfer of money is outlawed. Money can only change hand through registered business transactions." How do you reason and imagine the economy of such a society? Would your behavior change if this law applies to you?
