The cool part about focusing on community resiliency is it increases the mental health and well-being of the community members, as well as helping the local economy by focusing on self-sufficiency!
In many cases, there are benefits to scale, but the optimal scale varies from one setting to another. Sometimes, the optimal "unit" is your block. Sometimes, your village. Sometimes, your family. And sometimes, yeah, just you.
At a massive scale, things start falling apart again, because the government - or any other organization notionally responsible for the well-being of millions - is not going to be particularly invested in your individual outcome. You're just a small part of a statistic that might be tracked somewhere. You don't quite qualify for a particular benefit because of your unique circumstances? Tough luck.
Otherwise, we're either asking local government to invest in resilience or reinventing local government to ask this new body to invest in resilience. In either capacity, we are not investing in individual capacity, we're just trusting that the resources we need will be made available in time of need and sufficient to the needs of all.
community resiliency is also often overlooked in media - it's easier (and better marketing) to make a show about "preppers" buying merchandise. but the community aspect exists, probably even among those individuals, and gets much less attention.
but we live in times that make it difficult to build, find, and keep community. many people find individual projects more accessible. and in the end, individual capacity contributes to community resiliency.
the most radical (not reactionary) people i know are working all of these angles at once.
