If you have a house in the countryside, then water and food are relatively easy. You've got your own well and septic system for water, and plenty of room to stock up on food, plus you can supplement your diet by growing your own vegetables and raising chickens, fishing or hunting as seasonally appropriate per your local regulations.
The well and septic system require no real effort on your part once installed, though you may find harvesting your own food to be too time consuming or labor intensive to really be actually independent.
Lol. I grew up in a house in the countryside. Dealing with the well, water storage tank, and pressure booster pump were far from "easy". They required frequent maintenance and occasional large expenses. The well got clogged with sand. The pump motor burned out. The tank float sensor got stuck and caused an overflow (several times). The tank had to be emptied and cleaned. An earthquake caused a pipe to shear off and dumped thousands of gallons of water out of the tank. The pressure booster pump burned out. The pressure booster tank corroded and leaked. The water was hard and required a softener to prevent mineral buildup. Etc.
