Considering a comparison between a Communistic-type State meddling in private affairs of businesses (such as their opening hours, when they are allowed to sell certain things, etc), and the Antichristian probihibition on "buying and selling" - they seem connected, at least thematically.
Living in the strongly leftist-influenced Scandinavia where the State already defines the waking hours of businesses and consumers to a demonic degree, I can absolutely vouch for such an interpretation.
