Demand is affected by price. If marketing increased demand they could sell the same number of units for a higher price.

...and possibly with less profit, because marketing would eat away at the margins.

They'd have to raise prices just to keep the margins the same.

The important question is how much demand does each dollar of marketing create. It would be poor decision-making to just assume marketing is a bad idea because they are already able to sell through everything at current prices. Presumably there’s somebody doing that math at the company.
