Marketism/contradictions

A contradiction in free-marketist logic:

1. The state monopoly on force is an affront to Liberty.
2. Any use of force by the state is antithetical to Liberty.
3. The only valid commerce is free association among individuals.
4. State chartered corporations provide a limitation on individual liability, backed by the state's monopoly on force.
5. This limitation on liability allows individuals who acquire a state incorporation to avoid their debts to other free individuals.
6. Therefore, corporations are antithetical to Liberty.
7. The only forms of commerce consistent with Liberty are sole-proprietors and general partnerships, in which the individual owners carry the full responsibility for their financial liabilities.
