I have not read spooner. That being said, force is inevitable. It is the automatic default in any human interaction save when it is tamed by other force. So long as avoidance becomes impossible (such as in large and populous civilizations) there will ALWAYS be force, be it defensive or offensive. Governments are instituted amongst men so as to subordinate force to its proper retaliatory purposes.
But I will agree that this leads to a state of entropy wherein, eventually, whatever power a state possesses becomes like the One Ring and brings its elites into tyranny over the generations until a nation is ruled by sniveling cowards and snakes.
But then that state falls and, from the anarchy, comes more violence. There will ALWAYS be force. Even in a totally anarchic system, the moment a man is robbed and robs back what is his, or rescues the stolen property of his friend, that man BECOMES the state. Whenever one group of people come together to fight off barbarians, that militia captain BECOMES like government.
