Even if Amazon actually removed it from the economy by putting it under Bezos' mattress, that would boost the value of all remaining fiat, increasing purchasing power for everyone else. So consumers would gain a temporary burst of value, which they can utilize today; when the state then devalues fiat over time, Amazon's money will lose value, while the consumer will have locked in that higher purchasing power.
There is no scenario under which Amazon actually hurts anybody by 'removing' money from the economy. Money and wealth are not fixed sums anyway.
