Capitalism is the only social system based on the individual being sovereign over his own life. You own your labor, property, choices and ambitions. You may produce, trade, persuade, associate or walk away. You may not initiate force against others. Every statist alternative reverses this principle. Whether power belongs to a monarch, party, majority, bureaucracy or collective, someone gains legal authority to subordinate your life to purposes you didn't choose. Anarchy doesn't solve this by abolishing rulers. Without objective law and a government monopoly on retaliatory force, competing private forces determine whose rules prevail, a market in coercion. Capitalism leaves government one legitimate function: protecting individual rights. The individual governs his life. Government governs the retaliatory use of force.
