"In most climates, it takes an acre of conventional crops to feed a person. You'll need more like 10 acres per person if you want to do the decrepit/abandoned look, and it will take much more time, too. I really wish folks would actually TRY various agricultural techniques before recommending them to others."

I'll assume you were responding to me. The point I was making was not so much to assume self sufficiency, but to misdirect interest in the huge stockpile you're sitting on. Growing 'weeds' is a bonus and hard to quantify that you are NOT really living of the weeks, for the very reason you mention.

Yes, this is a short term strategy. If it gets to this, my 'half dead' looking family will be half alive more than those actually... not. Clearly unsustainable, but I suspect quite some time would be needed to find a new balance. Sadly, as my countris economy is still booming, land is very expensive. I need a strategy I can actually afford, and this is just one of 3 I'm going with.

" These 2 paradigms are difficult to maintain on a daily basis. It takes a lot of energy to focus on both. It is kind of like commiting to opposing realities."

It IS hard. But I have found it necessary, if only simply because we individually cannot poses the information needed to make accurate decisions. When will the economic collapse and PO shocks hit? In 3 months or 10 years? If in 6 months, you'll be stockpiling food and looking at leaving the city. If 10 years, it might be best to 'work hard \ save hard' to get a better landing. Not knowing is what caused me to implement 3 different strategies all in parallel. I concurrently stockpile and prepare, have a special rental investment remote from the city I can inhabit later myself if needed in a pinch and trade\invest\save for a land purchase. It's frustrating and to an extent inefficient, but the best strategy I can come up with.
