Capitalism is just free trade with respect for individual rights.
The State is the seed of corruption that makes violations of individual rights acceptable for a select few, allowing people & organizations to grow at the expense of others instead of by trade & mutual exchange.
You have things backwards. Govts grow & dominate. We are naturally a social species that cooperates through trade. Social behaviors are voluntary. The coercion & theft that form the foundation of all govts are anti-social behaviors.
