But I somewhat disagree that there is no requirement for players to perform long distance travel. Pirate massacre missions can very often take you into a system with a distant star leaving you travelling for hours tracking down pirate lords when they spawn at secondary stars. There's no easy way to discover this before you accept the mission, since they don't spawn until after you have arrived at the system,.
First if you do massacre pirate lords missions, which in itself does not exists, you either massacres pirate faction ships, or you kill pirate lord.
Massacre missions takes place in a specific target system, so if you accept hunting pirates in a system with long distances, that is on you. you accepted mission into that system.
If you are talking about killing Pirates Lords, then these can move to a neighbouring system, so there is random risk that this can be into a system with long super cruise distance. BUT this does not happens "very often", as you claim. Ontop of this, the chance that the system you directed to, would have even longer super cruise distance than Alpha Centauri has to Hutton Orbital is very unlikely, as that is the reasonably conclusion if you are to be "travelling for hours" to the mission POI, or another more likely explanation is that you are flying slow, and if that is the case, who are to blame that it takes hours for you reach your destination?
But the again, the most likely answer is that you massively over-exaggerated this, both how often this happens, and also how much time you have spend when this happens. What was it you called this kind of thing, Hyperbole...
And you still have the option to abandoning those missions, if the super cruise distance turns out to be to far away for your preference of how much time you want to spend on this... You obviously does not do this for the credits, as you have repeated that earning credits are easy... and if you are after the mission reward, it is not uncommon that if you abandon the mission, you will find another mission with the same reward. And if it was a mission with a rare reward then you decide what is rather do, try your luck on a new mission or stick with this one? but if the reward is rare, then you are likely in the wrong station/system for that particular reward...
