The government should also build massive amounts of housing. Everywhere of all types - apartments, townhouses, single family. After built transferred to the residents as coops.
Many/most corporate owners are individuals (as per the linked report). See my comment here:

Yes. Cap to 0. Until we get data on the breakdown (what percentage of rental homes are by owners who own 1, 2, 3, etc), we don't really know. It won't be easy to determine because a lot of RE investors create a new LLC for each property they own.

That is saying let's eliminate rentals entirely. If nobody can own a rental, there can be no rentals.
Some people do prefer to rent. I wouldn't, but I know people who truly prefer that.
It is, of course, an extreme scenario. As I said, this is absent good data. If we get a sense of the impact one would have if we limit it to 1, supported by data, sure - cap it to 1.
