This screams of the Hegelian Dialectic. They, the controllers of humanity, intend to further enslave us much more overtly, through a mechanism such as the 'social [credit] score'.
What we see in the video is the problem demanding a solution. We, and this, is the reaction - something must be done. The solution is to inhibit access to the shop to known & verified people only. To realise this, we will submit to a social credit system, one in which privileges will be assigned and verified in real-time.
Access to premises' will be through a gated walkway, not so dissimilar to the entrance of a high security event or building, where a realtime access check can be performed of your score and/or legal access privileges assigned to your person.

Imagine being disallowed access to a store because you do not have the credits to purchase a single item from the store.
Imagine being disallowed access to a store because the owner deems only those with score X be granted, those below be damned.
Imagine being disallowed access to a store because it is outside of radius N miles/Km from your resisted home address. For no reason.
Imagine being disallowed access to a store because you have not earned the assigned privilege to purchase items from a store of this type.
Imagine being disallowed access to a store because of last nights Reddit comment, perhaps whilst intoxicated, then reduced your score.

This is why digital currency, later to be a one world DC, and what it provides, is central to the controllers' grasp of humanity.
