That's the Socialist Calculation problem point, which is the primary problem.

Another problem is that the new money acts like old money at first and distorts prices as it works through the economy. That's the Cantillon Effects issue.

Since governments are historically terribly inefficient capital allocators I would say gov spending and money expansion are a net drag on wealth creation.
