In a centralised system, a disaster is a calamity
Disasters happen and smallism provides a path for rapid recovery after such a disaster
Smallism is based on the belief that calamities will happen, on local, national and international scales and that a social structure needs to be naturally designed to provide as much resilience as possible to withstand these shocks if our nation is to be prepared for the unexpected.
The networked and distributed nature of Smallism means that should our Ward suffer a disaster, any damage is can be contained, limited, and mitigated. For example, because there are wards with similar land resources who also produce leather, the effect on the supply chain is minimized.
Contrast this with a situation where our ward is the sole producer of leather and consider the knock-on effect on producers who manufacture products from that leather, including loss of future customers, loss of earnings, costs of restoring reputation (often in futility) and finally job losses and closure.
Clearly, having a flexible choice of supply is the preferred option for secondary businesses reliant on leather for their continued existence.
Currently, our social systems are heavily dependent on narrow supply chains that increase the chances of major supply problems when things go wrong. For example 3.74 MILLION-TEUs of containers came through Felixstowe in 2011 (ranked 36th busiest in the world) so if that port was disabled for any reason the country would grind to a halt, in part because the UK relies on the import of raw materials for its manufacturing industry, including metal supplies for the military and food.
By becoming more focused on fundamental self sufficiency as a network the country, will reduce its imports, starting with food, because of the focus on fundamental human needs, which will improve the trade deficit and keep more money flowing within the UK, after decades of politicians frittering away our Nations wealth for the tears of children.
 The trade-off against cost is covered under the economics of the modern society.
