I'm not well read enough to offer any reading recommendations for direct critiques, but I am reminded of the single footnote in Malatesta's 'Anarchy', where he gives a nice concise explanation of alienation/reification (I think): -
'The metaphysical condition, which is a disease of the mind in which Man, once having by a logical process abstracted an individuals qualities, undergoes a kind of hallucination which makes him accept the abstraction for the real being.
I'd argue that the concept of self-ownership encourages you to rationalise your conception of yourself, to accept an abstraction of yourself as the self-image that you relate to, and because we're dealing with ownership, in a capitalist/propertarian society, that abstraction of you is a specific kind of abstraction - you as a commodity. Thinking of ourselves as commodities has some serious implications, that i'd argue go beyond the immediate issue of conditioning us into being willing wage slaves, marketing ourselves in the labour market.
I'd argue that it also encourages us to situate ourselves, every aspect of our experience of existing, first and foremost in an economic context, as an economic action - our ambitions become careers, our desires become products we have yet to buy and our play becomes leisure. The concept of self ownership is one of the elements of capitalist civilisation that conditions us into a mindset that is useful to and functional in economic society, whilst subverting the desire to feel autonomous in such a way that it deforms the individual's power to be genuinely autonomous in thought, feeling or action.
As a side note, I'm pretty sure I've invoked the concept of self ownership on here before, so I'm glad this came up, it's not every day you get to seriously challenge/correct a way of thinking you've been conditioned into :)
