There are perfectly good definitions of capitalism in dictionaries and economic text books; I prefer not to define the inherent problems of capitalism away by distinguishing between "good" and "bad" capitalism. I like private property and voluntary trade, but that does not define capitalism, it is called capitalism for a reason, and I think there is a lot wrong with capitalism.
But I am not willing to discuss this until I come up with something better, in the anarchic, voluntary, distributed, semi-socialist, workers owning means of production individually or in self-chosen groups, freely trading and having private property direction (vague enough 8-), so let's agree to disagree here. It'off-topic anyway.
