Agreed, and I'll be honest, I'm a city folk

But both my parents were farm kids, and hearing their stories, I have an appreciation for what it takes to grow food and truly "live off the land". It may be cool from a gaming perspective to be decked out with some sleek black rifle with a bunker full of MRE's, foraging city remains for what's left over, and dueling it out with bandits. But at some point, you can't go it alone...not even with a typical family. Maybe with a somewhat large extended family (my mom had 7 other siblings, 2 uncles, and all their extended family living in very close proximity to help out with the farm....and even then, they would get locals to help harvest the crops and would pay them with 1/3rd what they harvested).
I think our modern city life style and even suburban life style has made us neglect our neighbors. Most houses don't even have front porches anymore. So, we've built in this idea, especially in big cities, that strangers are to be met with caution if not avoided altogether.
I've speculated that rural folk will survive an apocalypse far far better than city folk will.
Eventually he will run out. Also, if word ever got out how much food he had, he'll become a big time target. And lastly, how nutritious is that stuff? Even if he has a variety of MRE's, I'd be very suspect at the nutritional value of pre-packaged food that has a shelf life of 5 years.
But who will maintain those wind turbines and solar panels? Once the people die, there will be a shortage of people to maintain, repair and build that kind of equipment
