That's true in the short term, but in the long run the cost of goods tends go up, or down, to match the amount of money available to buy them.
And if the goods, or their components, are imported then their cost in Pounds obviously reflects the value of the Pound against the value of the currency of the country from which those goods are imported.
A measured increase in the supply of money is fine, but if it is overcooked - and I think there is a risk that is going to happen - then there will be problems over time.
