It is possible to overproduce unambiguously good things such as food, clothing and shelter but it is not so efficient neither for the government nor for private companies. When you overproduce whatever item or items, according to the market rules, price of the item or items will go down and inventories will grow, the government or companies wil lose money and reduce production for the next period, otherwise they will experience bankrupcy. The other thing that we have to bear in mind is that food is not unambiguosly good. When it is eaten properly, it is clearly good but consuming so much food can cause morbid obesity. For a man weighing more than 320 pounds a little more food consumption might mean dying of a heart attack. We can do the same analysis with other products.
