I would say you use the wrong definition of anarchy, try reading some of this:
Infoshop.org - An Anarchist FAQ - Version 11.9
to realize that anarchy is a system of equality, and therefore also an extreme utopia. However most people seem to use your definition of it, which is sad, because it only makes the true anarchists look bad.
The "economic anarchy" you talk about I think should be referred to as neo-liberalism, which is the system where the only power is the economic power (sort of, no governments). But in pure anarchy an oppressive economic system would be "forbidden" (i.e. if there was one, it would not be anarchy).
I too think that if there should be a system of economics similar to what we have today, it needs tons of regulations and laws to be considered "good" or "fair" at all.
