They are wrong however. To take the food example, the existence of processed food production creates artifacts like food deserts. If you are privileged these things don't effect you as much as you get more agency.
Just the existence of quick to eat and prepare foods are going to put limits on how long you are going to be given for lunch and dinner. Even if you wanted to prepare fresh food, the system is going to make it difficult since it becomes an unsupported activity in terms of time allowances and market access.
I made no judgement about the quality of processed food or where the different options rank in terms access to calories and nutrition, or what is actually feasible. It was simply about how changes can become mildly to severely obligate to certain populations in our economic system.
