this is fabulous. so much effort has gone into finding new (cheaper) places to shift rubber production, and also to avoid disease, and it's always been precarious. Lots of human suffering involved in rubber, and the transport system we currently have is dependent on at least some quantities of natural rubber. If it could be produced sustainably, at different latitudes, in different parts of the world, wow.
Interesting. I also like the idea of deriving sealing rubber for jar lids from something that, in its natural state, is edible.
I mean, I think that making shoe soles on a homestead might be feasible, if part of your system includes as part of the business plan a cobbling business, or if you have or wish to acquire those skills as a hobby, but probably not tires. I think, however, deriving a liquid latex product that can be painted on the inside tops of jar lids for canning is definitely attainable on the homestead scale.
A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.
