The reference to “buying from Naomi” is difficult for receptors to grasp, not only due to the cultural disparities which lay behind this conclusion of Boaz (as outlined above), but also because there is no previous hint in the text that Naomi was actually “selling” her land.
In fact, this would seem to be a very strange thing for a poor widow to do, for how then did she expect to support herself?
