Your core assumption is that flooding the system with money will cause inflation. However, in many modern cases we do not see that occurring in the traditional sense. Recently CPI-based inflation is non existent in the large economies of the world, but asset inflation is, which exacerbates wealth/income inequality and leaves the potential for a Japanese-style "Lost Decade" (which has been going on for much longer than 10 years at this point). Asset bubbles, misallocation of capital, and mortgaging the future to support the present are the pressing concerns with easy money that should be addressed.
