I think you might be misunderstanding how to cook with it.
Pressure cookers don't necessarily reduce cost. They reduce cooking time.
I agree that you are misreading the directions. Look at them again. My pressure cooker states that you can not fill above 2/3s full, as froth from the intermal boiling liquid may clog teh steam release channels. Many recipes call for a cup or less of water, and a steamer, or pan insert to hold the food, i.e. making cakes, dumplings, steamed veggies, etc. You don't want the food directly in the cooking liquid, but rather use the steam, heat, and pressure to cook the food.
To little liquid will simply cause the food to burn to the pan, not cause the pan to explode. Too much liquid can defeat the safety features of the pressure cooker.
Think about what goes on inside the PC. It's designed to release pressure when it gets to between 10 to 15 lbs. internal pressure, depending on the model you have. It will do that unless it is clogged, or the valves are stopped up. Even then, there is a safety release that will give before explosive pressures are attained within the cooking vessel.
