I have a bad back and bending over hurts. Statistically it will also start to hurt you someday.
Even if we ignore the pain, there is no way to organize food in a chest freezer effectively. To reach items on the bottom one must remove all the food that sits above it. This wastes time and effort that could better be spent on other things. Meaning the opportunity cost is too high, even if it saves me money on electricity.
Yeah, we have a french door fridge with a lower drawer freezer, and even with that being split into an upper drawer maybe 8" deep, and a lower one ~12" deep. Everything but the top layer and maybe one layer under that, is where food goes to die. And that setup is vastly better at this all than a 30" deep chest, except that when you pull the drawer out, all the benefits of a chest are lost. So (nearly) the worst of both worlds.
