A market is not people. It is the mechanism which a self-ordering system uses choosing between options. It does not require people to operate. But human society is a self-ordering system and consequently it progresses and evolves through markets. Despite the claims of the socialists, all human societies have progressed this way. No exceptions.
While markets are not perfect, they come pretty close. More to the point, they are the only mechanism which has been demonstrated to work at all. Perfect socialism is perfect stasis and states can only function at all in so far as they allow freedom of action to their citizens. Which is precisely why the West won against Communism. More liberty.
This is a truly astonishing statement. Markets operating without people? How is that possible? (And what would be the point?)
