The internal crisis can end the story of the civilization before it reaches the first step in the Kardashev scale.
The nation is before civilization. And for reaching Kardashev scale 1. The civilization requires all the resources that it can get. That it can create structures that make it possible to benefit its planet's energy. The first three steps in the Kardashev scale are the most difficult. Even if we think that megastructures like solar rings are humble we compare them to Dyson's spheres that cover entire solar systems. But those first-scale or first-step structures require lots of resources for the small-scale civilization. Making energy rings and other things is necessary for civilization. That it can start to control their planet's energy. In the Kardashev scale 1. There is one notable thing in the Kadashev scale. Each level requires the previous level. But each level in those scales forms the next level automatically. So civilization requires a Kardashev scale of 1. That it can reach Kardashev scale 2. In that version, the civilization starts to control the energy of thei
