> The good news is "society" isn't buying and selling houses, or negotiating rental agreements. Individuals are.
That's not really true. If you define "society" as "large groups of people", then they absolutely are buying and selling houses, and negotiating rental agreements.
In my hometown, over 50% of single-family houses are owned by major corporations. And some of those corporations are listed and traded, their stock exists in part inside wealthy and upper-middle-class people's 401Ks.
"Society" is absolutely buying up houses, and negotiating rental rates.
