If I order a cup of tea, you could argue that what I actually want is to achieve the goal of drinking something which has the taste, smell and general nutritional profile of tea. Theoretically, there might exist a cup of coffee that achieves this goal. But I've never seen one, and if you serve me coffee it's almost certainly not going to achieve my goal.
