At any rate, the capitalist farmer can cultivate soil A under these conditions, inasmuch as he, as capitalist, has such power of decision. The prerequisite for the normal expansion of capital in soil A is now present. But from the premise that the capitalist farmer can now invest capital in soil A under average conditions for the expansion of capital, even if he did not have to pay any rent, it nowise follows that this land, belonging to category A, is now at the disposal of the farmer without further ado. The fact that the tenant farmer could realise the usual profit on his capital did he not have to pay any rent, is by no means a basis for the landlord to lend his land gratis to the farmer and to become so philanthropic as to grant crédit gratuit for the sake of a business friendship. Such an assumption would mean the abstraction of landed property, the elimination of land-ownership, and it is precisely the existence of the latter that constitutes a limitation to the investment of capital and the free expansion of capital in the land. This limitation does not at all disappear before the simple reflection of the farmer that the level of grain prices would enable him to realise the usual profit from the investment of his capital in the exploitation of soil A did he not have to pay any rent; in other words, if he could proceed in effect as though landed property did not exist. But differential rent presupposes the existence of a monopoly in land ownership, landed property as a limitation to capital, for without it surplus-profit would not be transformed into ground-rent nor fall to the share of the landlord instead of the farmer. And landed property as a limitation continues to exist even when rent in the form of differential rent disappears, i.e., on soil A. If we consider the cases in a country with capitalist production, where the investment of capital in the land can take place without payment of rent, we shall find that they are all based on a de facto abolition of landed property, if not also the legal abolition; this, however, can only take place under very specific circumstances which are by their very nature accidental.
