That first sentence isn't quite right. I agree, personally, that every political system should be burned to the ground but, as usual, some Marx might give a slightly saner perspective here: the problem is precisely that there is a political system, which separates political personhood from private, civil personhood. Today, a group of people acts in social cooperation primarily through a political system. They may have an important social goal, like improving child nutrition, but the political system has already leeched the social power necessary for its achievement. Thus, any other social goals being worked out through the political system, such as economic growth, national security, even personal liberty, are at odds with the social goal you're concerned with, simply by nature of having to work through a defined, singular system. You can only push and pull a lever in so many directions, no matter how complicated and multi-axial it is. And as a sidenote, the political system itself doesn't have goals, even if its initial creation did have specific goals. They inform the system, but are not properties of it.
The intent of communism (esp. with the abolition of the state) is not, contrary to many views, some evil dictatorial master plan, but simply to put social power back into the hands of the people, allowing the existence and implementation of real social priorities, such as child nutrition.
"the problem is precisely that there is a political system, which separates political personhood from private, civil personhood."
I don't know about that! I have plenty of Politics in my life without it needing every fibre of my life to be infused with it, thank you very much. Rather, I shall go into the office tomorrow and go about business with Ron Paul supporters and Occupy SF supporters alike, and sip espresso with them in the afternoon, and I think there's something fundamentally humanizing about being able to do that.
But then, I guess that's a classic divide, as I recently saw evidenced in this opinion piece: http://online.wsj.com/article/SB1000142405270230437150457740... on the fundamental differences in the outlook on life as evidenced by commencement speeches delivered by Barack Obama and by Mitt Romney.
I'll admit this idea of political-social alienation/separation is a very abstract notion, and usually meritless in terms of immediate practicality. But you've demonstrated the reality of the notion itself: "I have plenty of Politics in my life without it needing every fibre of my life to be infused with it, thank you very much."
The claim is that "politics" as a social activity separate from universal, daily human life is artificial and an accident of modern society. That is, in the Marxian ideal you would never think "politics in my life"—that distinction between "politics" and "my life" would be a meaningless concept, since "politics" would be a nonexistent concept. You are already an inherently social being, and politics is just a particular abstraction of that sociality which seems like a good idea in modern society but prevents an "ideal" society (for many formulations of "ideal").
Think about it this way: when you vote, you are acting socially through politics. When you perform a business transaction, you are acting socially through economics. When you go to work (or leisure) with people of different opinions, you are acting socially in a way that we generally just describe as social. All these things are inherently intertwined, but modern society has done a good job making them seem separate and distinct; it has invented terms to distinguish the first two types of social activity, and has imposed rules on them. The third example doesn't have another word because it isn't consciously regulated by society—there is no abstraction for day-to-day interactions with other people. Thus, a Marxian ideal sees no abstraction for any other types of interactions with other people. They all collapsed into one: there is no politics or economics, which are abstractions of sociality.
I'm not proposing any particular change in modern society that would bring politics "into" your life, merely presenting a way of thinking about politics and sociality that explains why child nutrition (and numerous other social problems) are not also political problems.
