Re: Collateral Damage from all this.
Farmer's markets are good, but you have to live close to the source. Imagine being in, say a London or New York city and trying to find a farmer's market.
I grew up in East Anglian countryside, on a farm, surrounded by farms and farm shops.
Its 50x easier to find a farmers market in London than it is in the countryside, because "farmers" (traders) like to come to areas where there are lots of people, and not lots of farms - its good for the margin.
There are traditional, established markets like Peckham, Walthamstow and South Ken, but there are also irregular artisanal farm traders setting up shop all over the place, eg in Stratford shopping centre on a Sunday, the regular market is replaced by "french"* farmers.
