These are very odd things to say. A domestic refrigerator and cupboard holds a week's worth of food easily, you don't need 3/4 acres for that. Temperature management is easier not harder in a larger building. As is good roofing. The idea that when someone else says "the store is nearby" they mean "there is literally only 1 store that I can possibly reach" is also a creative worst-case reading.
IDK, this feels more like a dump of ignorant projected fears than a serious criticism.
