Yes, one would definitely have to factor ease of access to huntable lands/fishable waters, distance from home, financial components of gun purchase/maintenance/ammo/fishing supplies, fossil fuels expanded, licensing expenditures etc. etc. Only under certain circumstances could I see hunting/fishing being a viable and economical model for subsistence relative to the availability of food as it relates to modern society in the year of our Flying Spaghetti Monster 2015.
It's probably just more an excuse to get out of the house. One could reasonably discuss the potential health benefits of a hunting/fishing based diet if cooking methodologies are included.
