The capitalist cannot resell the laborer as a commodity because he is not his chattel slave and the capitalist has not bought anything except the right to use his labour-power for a certain time.

Context

“By the transformation of money-capital into productive capital the capital-value has acquired a bodily form in which it cannot continue to circulate but must enter into consumption, viz., into productive consumption. The use of labour-power, labour, can be materialised only in the labour-process. The capitalist cannot resell the laborer as a commodity because he is not his chattel slave and the capitalist has not bought anything except the right to use his labour-power for a certain time. On the other hand the capitalist cannot use this labour-power in any other way than by utilising means of production to create commodities with its help. The result of the first stage is therefore entrance into the second, the productive stage of capital.” source
