It's also the smallest community unit that we can reasonably be broken up into whilst still reproducing labourers for the economy.

The more society is ground down and split apart the less we can help one another out of solidarity, and the more we have to spend on housing, transport, and every other appliance that needs to be duplicated for each separate dwelling, and the more dependent we are on money, capital and the state to provide for our needs. The lonelier we are, the more profitable we are and the less power we have.
