I don't recommend certainty regarding much, but will leave that to you to ascertain per your obvious intelligence and experience.

The paradigm shift ongoing in various technologies decentralizing means of production is pregnant with potential, and I hope you carefully consider 3D printing, aquaponics, and similar mechanisms that prevent your production from being subject to vampirism while enabling access to an ever increasing set of goods and services that you can make yourself, or with a little help from your friends.

A half dozen people with gardens and aquaponics can mutually contribute to a far more varied and useful menu of food than any one of them might produce.  Similarly, several folks with 3D printers using different materials can also vastly increase the products they can avoid parasitism by sharing between themselves.  

When you swing, swing for the fences.
