Why the anti-capitalism focus?

Hi,

I've come to anarchy via Austrian Economics (reading Mises, Rothbard etc.) and the US Libertarian movement. Reading this work and others I started to see the State as an institution that can only exist with the threatened or actual use of force over the 'free' individual, something that I find immoral and wrong. Hence, I started calling myself an anarchist, to signify my anti-state position.

However, reading this : http://www.afed.org.uk/organisation/aims-and-principles.html I was slightly bemused to see that the AF seems to define things primarily in terms of a war against capitalism. But I'm struggling to understand why if you're an anarchist you would necessarily be anti-capitalist, something which has at its core the freedom for consenting individuals to trade with one an other without the interference of the state.

But perhaps the more perplexing thing is that we don't live under a capitalist regime anyway, so being anti something we don't have seems a little redundant. We have some kind of capitalist/corporatist/merchantilist/socialist and increasingly fascist hybrid, something that is a long way from laissez faire free-market capitalism.

Perhaps someone can enlighten me on what exactly is wrong with the idea of being able to trade freely with one and other?

Thanks,
