It’s not a coherent argument, people just don’t like paying rent so they lash out in frustration. If you can’t own you have to rent, if you have to rent you have to rent from someone. It’s just a fact of life. Just like food is also a requirement to live and you need to pay someone for that too if you’re not self sufficient. There’s good people selling food and bad people selling food. It would be dumb to consider all food merchants evil in principle just as it’s dumb to consider all landlords evil in principle.
