This argument is absurd. It takes the obvious truth that causation will certainly lead to correlation and blindly flips it around and claims it's somehow profound. Just bad reasoning from beginning to end. The correct reasoning - causation leads to correlation - is the basis of all science. When scientific theories are evaluated, the razor is a check that the theory correctly predicts observed results. You can't cook up a theory that fits a set of already known data and claim you have formulated a causal relationship unless you can then predict the NEXT results over a substantial set of trials.
