The immediate design of the game itself ensures that there is griefing - Even if the game didn't have weapons which could be fired on other people.
Take average griefer X - has nothing better to do, he goes around finding 'care bear' miners - your typical farmer, running macro script 1.
He now proceeds to bump your craft constantly using a macro into the sun.
Farmer ship blows up - and since this must have progression paths - an expensive leveled up ship goes bust, while the griefer goes of laughing all the way back to 4chan or SA.
