Thank you for your question.
Indeed, the study you quoted is interesting. I'm inclined to say it's a rhetorical question, because quite simply, if we say that housing is a commodity, it's no longer a human right.
Having a roof over one's head is the foundation for a decent life, one where you can start a family and thrive. Without it, the rest disappears. People wind up with physical and mental health issues and have significant difficulties raising children, who, in turn, have trouble at school.
Stable housing is essential, no matter where in the world you live. I truly understand that investors want to make money. In the current system, they're doing great, but it shouldn't come at the expense of others.
