This seems like a very liberal conception of freedom - Berlin's negative liberty.
The freedom of, say, a family to have a day at the beach depends on the labour of a bunch of other people - the bus driver, the lifeguards, and for that matter the people who built the bus, refined the petrol, created the sunscreen. As appealing as I find the idea that socialism would transcend the commodity form, I don't think it means transcending the division of labour. So I'm not sure about this argument that alienation is the real enemy and people who just think of socialism in terms of redistribution are missing the point. Or are the bus driver and the lifeguards just doing it as a hobby before they are off to fish in the afternoon and criticise after dinner?
