It's only nonsense from a game perspective. Historically (in both Real World and game genres), Pirates have always been underpowered when compared to their Naval counterparts.
It's very much nonsense from a game perspective which has historically been a oft used reason for adding or changing ships of other fleets.
You're right that historically pirates were weaker but that had more to do with available resources, not through any "we're good enough to take down a merchant, we don't need anything better". As Poi said - being limited to lower priority makes sense since they don't have the resources to acquire the high end ships, but ships in a priority level are supposed to be relatively equal to any other ships of the same priority level. That's why the number of fighters in a flight are calculated based on how good it is. It's also why placement in a PL is based on how good a ship is. (Raid - White Stars aren't raid because they're the same size as Novas...)
This is one topic that I will agree with Matt that Raiders should be limited and strongly limited, always the underdog in the grand scheme; but will always disagree that they should be deliberately under powered in a specific Priority. I'd even be ok special rules for a campaign like - "Ships cost double for Raiders" to force an artificial representation that raiders don't have access to government subsidized dry docks, they've got whatever they can scrounge up.

Priority Levels! Let's keep ships level in each!!
EDIT: I'm going to point out the "deliberate" part of the under powering. I think that's what really got under my saddle blanket!
