Pirates are part of a chain:
Without pirates there'd be no bounty hunters.
With both gone all there is to do is explore and trade, soon all interesting exploration targets are explored up and all good trade routes come crashing down.
They are necessary, unlike the swearing and exploiting
Getting away from pirates is currently too easy. Submit to interdictions, boost away asap deploying chaff/HSL and in 15 seconds your FSD is up again to run into SC.
If they repeatedly interdict you randomly drop out of SC shortly after entering and hope they pick a different target. - Turns into a game of cat and mouse that's quite fun on either end.
Edit: In my opinion!
