The packaging metaphor is a good one, but.....
Most people are turning to basics (permaculture if you will) because the pre packaged life is breaking down.
And even if you keep the packaging metaphor going, the reality is you either;
1; Spend a fortune for a car under warranty, (which defacto means you have a pre installed mechanic). For a remarkably short period of time after which you need to spend another fortune.
2; Or you have a (relatively) cheap car and an expensive mechanic, or a series of inexpensive lousy ones
3; Or you have a car and a long history of back country breakdown education, and greasy trials, with long country walks and desperate pre dawn calls for assistance, that have taught you to do it your self
Permaculture to my poor mind is the third option.
If you would like to try it in the second instance, than you own land and hire a professional gardener / grounds keeper, cook (to can /dry /package, all the largesse!) and a carpenter or two to create storage space. Or offer shelter to a series of people whom may (or may not) have good ideas, good work ethic and are willing to invest their future in little more than temporary shelter.
Or to keep the packaging metaphor intact,..go with option #1, proceed to the Good Food Store and buy organically grown veggies, free range eggs, and grass fed beefalo as needed
For many "permaculture" seems to be a revival of "back to the land"
To me permaculture is; Build once, Harvest for generations....regardless of the playing field you choose to build on. As an exclamation point to that, planned obsolescence, and hybrid (no second generation crop) crops, are fraud.
