I would make the argument that it could actually be a means to align with affordable housing (although that would likely be very difficult in this current housing market). Managing a property is a service, you have to manage vacancies, repairs, rent collection, etc.

If you don’t offload this to a management company and do it all yourself it is technically feasible to make a profit from the labor of managing the property even when charging below market rate for the property (difficult to do right now, but after owning the property for a period of time definitely possible).

If you were to do this you would be directly combatting the affordable housing problem by introducing competition at a lower price (it would be a drop in the ocean, but it would be fighting for affordable housing).

I’d disagree with the notion “it has to”. The chilling effect on a large number of new wiki contributors could be considered more detrimental than weakening sock puppet protection. (IE if a huge country suddenly started jailing people who make edits not considered state-approved)

I suspect there are plenty of ways to allow new accounts to make edits on a smaller subset of articles until they have passed some threshold of trust which could minimize the sock puppet abuse.

Point is everything is a give and take.
