Context:

During the early days of the Covid-19 pandemic, the drastic lockdown and social distancing defence marshalled against it has wreaked havoc on many economies across the world - e.g., furloughing of workers or outright loss of jobs have been some of the most consequential to many families. As part of popular mitigating measures against this negative consequence, some governments have put a moratorium on eviction of tenants who are unable to pay their rent, with a commitment by the government to pay 2/3 of these rents in some instances.

Question:

Suppose this was exactly the measure that the SA government took, what has the government effectively done to the rental housing market in SA?
