That is one way to look at it. Another way is that you are paying (indirectly) for infrastructure and (directly) with subsidies for some people to lace your soda with high fructose corn syrup. Or to dry up the land by siphoning all water to make some stupid almond milk.
Yes, the web of subsidy is wide and complex, but not all subsidies are for the same reason.
For example, the fructose corn syrup subsidies exist, as far as I can tell, in order to on-shore agricultural profits and ensure sufficient slack in the domestic agricultural system to ensure that restrictions on imports of food, such as in the case of war, would not seriously affect the USA. That is, it's a subsidy towards food security.
