While I agree with this sentiment in theory, we've been hearing this since QE started more than 10 years ago and we have not seen the rampant inflation that was promised as a result, and there's been more than enough time for it to manifest by now.  I do think that taking runaway inflation as an inevitable given at this point is more folly than it was previously considering the repeated failure of the doom-sayers who were everywhere after the housing collapse.
