Why would you make such a ridiculous assumption? If the demand goes up now, producers strive to increase supply to meet that demand. Why would that change?
Why do you want to see the current system continue? What is your stake in it? Is your narrow self interest so overwhelming that you'd stand in the way of such a positive change for good, for liberty, for prosperity?
What makes you tick?
I can make a much better case that the prices would stay the same than you can make for prices dropping.
