Nah, private propery is a silly concept, especially when it’s essential resources.

We were all shocked and appalled at people hording masks, sanitiser, TP, food etc not so long ago. Sitting on TP you aren’t using while someone else goes without is absolutely trivial compared to a house/land.

Using a thing is part of what grants you rights to it. People deserve a chance to explain why something is unused, and if it is temporary they shouldn’t lose rights (e.g. medium term contract away from home, pending works, social obligations etc) but multiple homes and one vacant? Sitting on something to try make cash? Nah not yours anymore.
