It stops any leakage of volts and thus stops a possibility of a flat battery. Also if the boat is not earthed out properly it cuts down on any electrolosis which will eat away at your expensive metal bits that hang under your boat! or other boat next to yours. It cuts down the fire risk as well!
All good reasons. But it does leave the question of 'what if the bilge pumps need to operate?' But then you can also argue that even with the pumps 'live' and they started, it wouldn't take too long 'till the battery was dead in any case, unless shore power was connected and the battery charger on.

Automatic bilge pumps should have a dedicated "always on" supply. In well maintained modern boats they should not need to operate frequently. If they do, something needs attention.

If a problem occurs and the bilge pump needs to operate, better a flat battery or two than a sunk boat.

And if you have a separate bilge alarm connected to an outside light/siren that operates slightly later than the pump - ie with a float switch mounted higher it might keep the water level under control long enough for some one to notice and take action.

Providing they didn't interpret the alarm as just another annoying, over sensitive, movement sensor alarm....... like slapping mast halyards, on a windy day!
