Agorism is not magic and there will always be people who try to unfairly control others. As an extreme analogy: No matter how many men desire to, or how righteous their desire is, they can never stop an omnipotent being from doing as it pleases with them. No political ideology or popular support could change such a scenario. Agorism itself is largely tied to the non-aggression principle, people should be free to do what they please so long as they do not infringe on the freedom of others. Anyone who infringes on the freedom of others is seen as a threat and attempts will be made to stop them, generally via private defense agencies. The rich and powerful could have their own agencies that try to allow them to do whatever they please, that is simply a fact of reality and nothing can change it. However nobody says that they will win. Look at the powerful agencies such as FBI and DEA, it appears as if they have been stripped of their power to oppress by a single man using open source software. Good and evil will always fight but thankfully there is nothing to stop good from winning many battles in what is likely to be a never ending war.
