I'll try and dissect your criticisms one point at a time and try to poke holes in your arguments.
>Historically, mercenaries are massive cowards. Once the tide starts turning against them, they'll desert and flee, assuming they don't get hired by the invading force.
Well, sure. But everyone is a massive coward at heart. Just because someone is enslaved into military service at the point of a bayonet doesn't change this fact. It doesn't take a deep understanding of military history to realize that routing or desertion is a universal aspect of warfare. As soon as one side believes they will lose they will flee from the battle to preserve their own lives, this has not changed throughout all of human warfare. The few times that a company of soldiers endured losses and defeat instead of fleeing are unique occurrences. I think it is worth considering that many times these extreme acts of selfless defiance against impossible odds were usually people defending against an invading force, consider the Alamo, the Gaulic Wars, the Winter War, etc.
>Militia
The modern world has numerous examples of smaller, weaker countries defending against aggressors who have greater resources to spend on aggression. Combined arms, air force, and navy are almost always needed for states that plan on engaging in state-to-state warfare, as they are tools that are needed to defeat modern armies in the field. The tanks and mobile infantry are needed to breakthrough enemy defenses and encircle an army, air force is needed to destroy organization and communication, and a navy is needed to facilitate invasion, supply, and to continue the requisition of the armaments of war that a massive army requires to function, but it is not the tools that a defensive force needs. Defense requires a far lesser degree of investment than attack, surface to air missile launchers are far cheaper to produce than modern jets, the only reason jets are produced is that they are armaments of aggression. Battleships and nuclear submarines are not defensive but offensive. These tools of offense don't mean victory, either, you only need to look at Vietnam and Afghanistan to see that a much poorer and less numerous force can exhaust an attacker until they need to retreat. However, in a stateles society, the people would be far richer and would be more thrifty in defense, people would only want to pay for what is absolutely necessary for defense. A billion dollars would go a lot farther in a stateless society than one beleaguered by a bloated state.
>Governments, with their fiat currency and monopoly on force, are quite good at delaying the negative incentives of their retarded actions until the next head of state comes into office, which decreases the incentive to act rationally. Also take into account that most democratic leaders are sociopaths and pathological liars (traits best suited to winning elections), meaning they're even less likely to make the rational choice.
You still haven't provided an incentive, only made the claim that they aren't rational, which is a whole other topic that is a lot more complicated but I will instead just contradict you by saying that they are rational. They make decisions that will increase their political capital. What use would there in attacking a society without a state? Modern history shows us that almost every war is preceded by some conflict between states: a border dispute, excluding each other from resources inside their country, ideological difference of state rulers, or what have you. If a state can exploit the resources in a stateless society as easily as they can within their own state, what motive could there be to attack? If there is no state apparatus in which to declare war and make peace with, how would you even go to war? If the people will never submit to the foreign authority then it would be only to the foreign state's detriment to be an aggressor.
Of course these scenarios are all predicated on the notion that statism continues in all parts of the world as normal and some geographic area all-of-a-sudden just dissolves the state, which I think would be difficult to imagine. If an anarchist world would to occur I would imagine it would not be isolated to one area of the world but be a global trend, a gradual transition as people are convinced that the state is not a necessary function of harmonious society. But even if it was only to happen in an isolated geographic area and even if it was eventually subdued, against all odds, by some foreign state then we would just return to how things are now but at least in the mean time there would of been a nice vacation from statism.
