I think the goal of each large group in present systems (government, the military, businesses, and households) is its continued existence. At the same time, these groups depend on each other for the same continued existence, and that dependence involves extensive supply chains and lots of energy and material resources. Since they all involve increasing number of people as consumers or employees, then they all need growth.
Thus, if these chains are disrupted, then crisis not only ensues but may lead to more crises, and mutual dependence is threatened. If the combined crisis takes place in the long term (due to limits to growth), then it is possible that each group will try to defend itself at the expense of others. For example, it can hoard or use physical force to ration resources, making sure that the most important groups receive enough of them. In this case, the important groups always involve themselves.
The result, then, will likely not be a centralized economy but a fragmented and feudal one. Citizens will not be defended by the military and the police. Rather, the latter will ensure their own existence by confiscating from citizens. Rather than laws from government, both will come up with their own rules which they will justify through emergency.
Given the cost of maintaining nation-states, borders together with means of long-distance transport will fall apart. Masses of people will be moving from one area to another due to economic collapse, and more so if that is combined with war and environmental collapse. In the long run, no country or region will be better off than others. Even the notion of nations and citizenship may not last, only affiliation to one local group or another.
Citizens can imagine that they will be able to defend themselves against the military and the police, but in most cases that will be either unlikely or temporary. As resources decline and those who were unable to accept limits to growth from the start (which likely means most people) become more violent and desperate, then the armed will soon start turning on each other. With that, mutual defense involves increasingly smaller groups.
Thus, one should probably not hope that the military, police, government officials, the rich, scientists, hoarded goods, firearms, etc., will "save" them in the long term. The best that can take place will be sustainable communities described here:
