That sounds dramatic. It is also bad economics. The claim treats scale as a one-way ratchet and ignores everything that makes real markets real: rising managerial costs, local knowledge, entrepreneurial discovery, heterogeneous land, and the ever-present role of state privilege. In a genuine market order, land does not move automatically to the largest owner. It moves—imperfectly, but decisively—toward those who can use it best under particular conditions, and those conditions often favor smaller owners rather than swallowing them.

Ronald Coase supplied the first devastating answer to Marx's "inevitability" thesis. A firm does not grow forever simply because scale can lower some costs. It expands only so long as organizing transactions internally is cheaper than using the market. Coase argued that as a firm spreads over wider areas, handles more dissimilar activities, and becomes harder to manage, the costs of internal organization and the losses from mistakes rise. Expansion stops when one more transaction is no cheaper inside the firm than outside it. That is the opposite of Marx's story. There is no law of limitless absorption. There is a limit set by coordination, error, and the price system itself. Even more importantly, Coase observed that taxes and regulations can make firms larger than they otherwise would be. So when concentration occurs, the first question is not "What did the market do?" but "What privileges did the state confer?"

Murray Rothbard's treatment of the law of returns makes the same point from another angle. With complementary factors held fixed, there is always some optimum amount of the varying factor; beyond that point, average returns fall. Applied to land, this means acreage is not a mystical source of permanent superiority. More acres under the same managerial attention, labor quality, machinery mix, or local knowledge do not produce an endlessly improving result. Beyond some point, coordination worsens and output per unit of the varying factor declines. In plain English: bigger is sometimes better, but only up to a point, and the point differs by crop, place, skill, and technology. Marx converted a possible tendency in some circumstances into a universal law. Rothbard's analysis shows why no such law exists.

Friedrich Hayek then adds the decisive epistemic objection. Economic knowledge is dispersed. Soil quality, drainage quirks, timing of planting, local weather patterns, relationships with suppliers, labor reliability, and the subtle rhythms of a particular place are not fully knowable from a distant office. Hayek's point was that prices help communicate scattered knowledge, but they do not abolish the advantage of "the man on the spot." That matters for land more than for many other assets because land is irreducibly local and heterogeneous.

Israel Kirzner extended this insight by emphasizing entrepreneurial discovery: markets are not static structures in which big incumbents merely execute a mathematical optimum; they are rivalrous processes in which alert actors discover overlooked opportunities. And Carl Menger long ago noted that where profits are available, competition itself tends to call forth competitors, provided barriers do not block entry. The free market, then, does not guarantee giant estates. It generates continual challenges to incumbents from people who know something the incumbent does not.
