This is a “defect”, says Marx, but it is unavoidable in the first phase of communism; for if we are not to indulge in utopianism, we must not think that having overthrown capitalism people will at once learn to work for society without any rules of law. Besides, the abolition of capitalism does not immediately create the economic prerequisites for such a change.
Now, there are no other rules than those of "bourgeois law". To this extent, therefore, there still remains the need for a state, which, while safeguarding the common ownership of the means of production, would safeguard equality in labor and in the distribution of products.
The state withers away insofar as there are no longer any capitalists, any classes, and, consequently, no class can be suppressed.
But the state has not yet completely withered away, since the still remains the safeguarding of "bourgeois law", which sanctifies actual inequality. For the state to wither away completely, complete communism is necessary.
