In Stellaris, specifically version 2.2 Le Guin, is a nearby starbase's Protection value enough to prevent ill effects from Piracy, or is there a benefit to assigning ships to provide Piracy Suppression as well?
This system isn't being patrolled by any fleets, and no fleets are nearby, so it doesn't have any Piracy Suppression. As a result its Piracy is slowly building up.
But because it's right next door to a fortified border post, this system has a huge amount of Protection - easily enough to dwarf the listed "Max Piracy", and in fact more than the actual value of the trade route. If I understand correctly, that means its full Trade Value will be delivered no matter how much Piracy is allowed to build.
My question is, what do I stand to lose (in terms of events or other effects) from not assigning a fleet to patrol this system?
