Power can be amassed behind the barrel of the gun but it will not last for too long as people will realize that the real power is with them and there can be the time when people will use that power against the very government that they assume should be protecting them. Capitalism and democracy can be considered as bad systems but the problem is that many other contender ideas can't be considered as better alternatives. There are actually good ideas for governance but when they are applied human nature gets in the way leading to massive failures. We saw this with the communism in the 70s and 80s. In the end, there is no perfect system it is how we use the system that matters most. In addition, the end should not be used to justify the means.
This is as Winston Churchill said, 'democracy is a terrible system, except for all the others.' On the face of it, we cannot disagree with this.
What I try to point out is 'democracy' is not what we think it is at first sight. Yes, we have free and fair voting in the West. But it is not real democracy when the voters are deliberately and completely misinformed. For example, how can voters stop the US-Saudi promoted war in Yemen when the only time they heard about it was when a school bus was blown up, which was really just the tip of the iceberg of the suffering from the war?
Since the center of our entire system is the money system, nothing around this center can be truly free of the state. In practice, being controlled by 'the state' means being controlled by the state-bank elites.
