Hunger is only a distribution problem in the sense that people in certain regions don't produce enough food to feed themselves or anything of enough value to trade for food. Which is a problem with the social and economic systems of those countries, something that can't be fixed externally (unless somebody wants to e.g. invade and depose King Jong Un..)

It is partially that and partially logistics. Food waste is significantly higher in areas where hunger is endemic because a lot of food never makes it to a market where it would be purchased due to poor transport links, lack of refrigeration, etc.

Housing is inexpensive in places where there are not enough jobs. Cities were born due to industrialization moving jobs to them, not because people suddenly wanted to become urban.

So, what individuals want has little to do with it.
