The currently accepted way of subtracting oneself from the capitalist world-system is by becoming a successful capitalist. If you work long enough and hard enough as a wage slave, then freedom is granted via retirement. Or if you get lucky with investments, then you're free. But the retired person is dependent on state-based systems, like Social Security & Medicare, as well as on other organizations that have contributed to their retirement funds. And even the independently wealthy person must diversify against ever-present uncertainty.
