Mr. Beer above stated that an increase in demand for Netflix would not increase the market price of Netflix. But because Netflix is a quasi-monopoly, they would be likely to increase prices to find the new equilibrium maximum profit point.
That is, he made a microeconomic argument which was invalid-- arguing that because Netflix's marginal cost is low the price elasticity of the product they supply must necessarily be low-- but this is not necessarily true. Netflix has some degree of pricing power.
I made no macroeconomic argument, and.. while I agree with your macroeconomic assertions... increasing the supply of money still increases inflationary pressures. If you're facing massive deflationary headwinds because of slowing velocity of money, sure, it may not be enough to cause inflation or even entirely prevent deflation, but it still is net inflationary.
