Humans made do for the vast majority of their existence without electricity. Somehow, I'm not that concerned.
Finally, I could tear up the abomination that is the yard and nobody would complain about it, because everyone would finally understand that lawns are a pointless waste of space that should be growing food on them or be habitat for more organisms than just humans with their soccer balls.
There would be survivors but it's different when you're a. competing with many many more times the amount of humans from before automation and industrial revolution, who would quickly strip natural resource (what happens when your local edibles are already gathered, fish, wild boar and rabbits are already eaten?), and b. Not coming from the right sizes prepared land. Even a quarter acre lot is not going to grow enough food for self-sufficiency, and most people don't even have that.
c. Don't have the knowledge to live like a pre-industrial human. There's a lot more variables than meets the eye for basic safety, it's why most survivalist and preppers (which is an awful, toxic masculine fantasy culture btw) focus on hoarding already made supplies and means to defend them. And even modern off grid homesteaders still rely on modern machinery to farm, to make the tools they hunt with, medicine when they get sick, manufactured oil for their lamps, ect, etc.
There's a reason that mass starvation happened when supply chains break down in modern history.
Deep dive into how hard it is to actually be self-sustaining aside, I do agree that lawns are pointless and I'd rather have a garden, and HOA lawn requirements are ridiculous.
