In addition to remote monitoring, central control over large systems clearly has benefits: quickly and automatically spinning up a power generation in one location in response to an outage or just increased demand in another one, or conversely spooling down generation in response to a large demand spike going away (many factories need to notify the grid before starting up or shutting down), shutting down water/gas flow upstream of a detected leak, or yes, working from home, which lots of people here regularly argue is a good thing.
You could absolutely make the case that it isn't worth the risk, but that isn't the same as not having benefits.
