Why functionalist arguments are not historical arguments

It is a fact that in Scotland landed property acquired a new value by the development of English industry. This industry opened up new outlets for wool. In order to produce wool on a large scale, arable land had to be transformed into pasturage. To effect this transformation, the estates had to be concentrated. To concentrate the estates, small holdings had first to be abolished, thousands of tenants had to be driven from their native soil and a few shepherds in charge of millions of sheep to be installed in their place. Thus, by successive transformations, landed property in Scotland has resulted in the driving out of men by sheep. Now say that the providential aim of the institution of landed property in Scotland was to have men driven out by sheep, and you will have made providential history.
