Adam Smith had already clarified free market refers to a market free from all forms of economic privilege, monopolies and artificial scarcities.
You are confusing market outcome with market structure.
Good point, however we can't miss the history which shows that free market are not achievable, in some fields of economic is seen as "fairy tale".
But where is the monopoly here? Nobody has a monopoly on housing supply or DRAM production.
Nobody is making an artificial scarcity. They’re producing as much as they can.
You can buy the exact same DRAM that the data centers are bidding on.
