Agorism is revolutionary market anarchism.
In a market anarchist society, law and security would be provided by market actors instead of political institutions. Agorists recognize that situation can not develop through political reform. Instead, it will arise as a result of market processes.
As the state is banditry, revolution culminates in the suppression of the criminal state by market providers of security and law. Market demand for such service providers is what will lead to their emergence. Development of that demand will come from economic growth in the sector of the economy that explicitly shuns state involvement (and thus can not turn to the state in its role as monopoly provider of security and law). That sector of the economy is the counter-economy — black and grey markets.
