why can't carbon be used to reduce metals of higher reactivity?

Metals like sodium,aluminium and magnesium are placed at the top of the reactivity series.
Since they have a strong affinity for oxygen, so they hang on to the oxygen so strongly that the carbon cant take it away.To extract these metals you have to use the electrolysis.
