Yeah, correct. Even if you do control 51%, it would be a big long term capital and operational expense to do so, so you'd probably want to play nice rather than destroy what you've built. Besides, even if you attack it, a new network will just spring up again, possibly with a different mining algorithm, making your old mining gear obsolete. Also, in PoS, another last resort "nuclear option" defence strategy would be to slash the nodes that attack the network through a hard fork. It's a "nuclear option" because in theory it's unlikely to happen, only used a deterrent. "Slash" here means to confiscate and burn their staking deposit on the new network. (The old one will continue to operate where the arrackers reside, thus a "fork")
