I remember this article being posted on HN. My response was basically: What prevents a single individual from taking all the free stuff and using it in a wasteful manner?

E.g. you get a car for free, only use it for one trip, scrap it and get another car for the next trip.

In the context of the post/video, I'd say the social credit system (the "calories card"). If you abuse the resources, your card gets zeroed out, and you're effectively banished from society.

In the example of the car that you give: cars are pooled anyway, and assigned for a trip, then returned to the pool. So essentially you always get another car for each trip, but you don't own it.
