Im basing my answer in these two comments:

Kys: You're asking this about the same universe as space pirates and you wonder why there might be delays

HDE-226868: In what I can only refer to as the Golden Age of Piracy, I'm guessing there weren't too many shipping delays because of piracy. In theory, it's a threat you can't predict. You can only hope for the best, and deal with it when it happens.

In the Golden Age of Piracy there was not quick communication, so what would you do? Wait for a letter sent via raven by other ship? Even if possible, with the delay it would be unhelpful so you just set sails and hope for the best.

Circa 2100 maybe you can´t detect those nasty space pirates (although you totally absolutely could, but let's say you can't because you want pirates to be a thing), but what you can do is to communicate with Earth with, at most, a few minutes delay.

Other spaceships might send reports of sightings or attacks, and your flight would be delayed for a few minutes/hours until the spaceport security (or the army or whatever) makes a whole DRADIS sweep, assesses the situation, evaluates the risk, checks with their legal/insurance department and finally gives the spaceport the green light, which kinda means "the protocol says the course is safe enough", so the spaceship could still totally be raided if you so please.
