Personal opinion comment on the grocery store vs the rural sharing models of food distribution.
*Savings in both system presume organized home storage, for both dry goods and and parishables.
*Savings in both systems are what has been saved and available for trade either for direct exchange or through and exchange medium of currency.
*Eating what is purchased presumes a solid knowledge of nutrition, and menu planning.
*Preparing bulk foods for the table presumes a well equipped kitchen, appliances, pots and pans, utinsils, condiments and seasonings.
*And finally, the savings require a life style where the surpluses of money, transportation, time, personal energy, knowledge and skills are all available at the same time and place on a consistent basis.
Getting all these ducks in a row even some of the time requires maturity and dicipline; and even more so in urban settings.
Planned and paced transitions between the current practices and some as yet undecided future practice will continue to require that I focus on where I am trying to get to and satisfy myself with small incremental changes. The chaos of attempting to move too fast has, at least for me, actually delayed many of the goals being met.
