<p>Why can't we just print money to build national infrastructure services such as an additional hospital for the NHS? This would create growth, allowing more doctors and nurses to come through but more importantly create additional bed space.</p>

Because increasing money supply will eventually lead to inflation. Consider standard monetary model:

Now this simple monetary model is oversimplified- in more modern models it’s expected money supply what matters but the main message stays same.

Also note that in the short run money is not neutral and monetary expansion can boost output but the channel is not really through public investment but through the fact that it helps to put “grease” on the wheels of economy in presence of sticky wages.
