The portuguese state has been pushing to pass legislation to be able to forcefully occupy empty real-estate. One of the announced ways this would be achieved, would be through monitoring of electricity/water/gas usage in the property.
This "solution" is supposed to solve homelessness and high rent prices. But funny enough, most or all ministers housing is excluded from this proposal. An utter disregard not only to private property, but specifically property of the common shitizen.
There's a good amount of pushback from all sides, but it doesn't seem clear the proposal will be rejected. This shows how property is seen by a socialist state, and the inevitable side-effects of market distortions created by state intervention.
