I am surely no doom-and-gloomer, but I got a real bad feeling:
Private well and septic - check
Several acres of fertile ground - check
Several acres of woods, plenty of deer and other edible creatures - check
Big cast-iron woodstove with cooktop for heat and cooking - check
Relatively little debt and only a small mortgage - check
Shotguns, rifles, handguns, ammo - check
Okay. Bring on the economic meltdown.
One thing missing on your list is medical self-sufficiency. A real tough one, unless you live in a commune staffed with ex-ER and pharmacy personnel, and associated matériel. I hope at least your well pump runs on solar or another alternative source. Grid power will be subject to easy sabotage.
Reading your check list, it sounds like you are living in my basement. I better go check...
