Yes, industrial-technological civilization is only possible due to cooperation of human beings at a very large scale. If that cooperation breaks down, everything goes back to pre-industrial technology, at best - and even that required a great deal of cooperation, as any examination of pre-industrial agriculture-centric society demonstrates. The provision of wood for buildings and ships, fabrics for clothing and sails, simple metal implements as weapons and farming tools, etc all required social cooperation and division of labor, which in turned required legal systems to prevent internecine conflicts from constantly breaking out. If that in turn fails, we're back to tribal hunter-gatherer societies, an unlikely option without a collapse in human population to the 10,000 B.C. levels. This is fairly obvious to anyone who hasn't been completely indoctrinated into the myth of individual success based on hard work - a myth largely promoted to justify the consolidation of wealth and resources into the hands of a small ruling oligarch class in the modern world, see for example Margaret Thatcher's line 'there is no such thing as society' and so on. That said, it's possible that modern technological developments might be able to create the kind of technology that could allow people to survive quite happily with minimal external inputs of raw materials, via extensive recycling of finished goods back into raw materials, use of incident energy (sunlight and wind), but the problem would be creation of the technological tools and maintenance of those tools, which would almost certainly require high-tech factories operating at scale. If those factories could somehow be miniaturized and also be highly adaptable (still in the realm of science fiction, no backyard chip foundries at present) then concepts like a self-sustaining Martian habitat could become more plausible.
