How could aliens have the ability to destroy us if they didn't have their own technological civilization?

Manufacturing spacecraft capable of traveling between the stars in any reasonable amount of time, if possible at all, would be an immense industrial undertaking, the pinnacle of not just scientific knowledge but societal complexity in order to coordinate the resources involved. Any alien race capable of doing these things must have also committed the sins that they're smugly damning us for, and to a far greater degree than we have.

Note that my comment specifically mentioned hive minds. A civilization has many cooperating/competing individuals. Most of civilization's problems are epiphenomena arising from this fact. What if most galactic factions aren't composed of many individuals, but are effectively one distributed mind? What if they regard our social pathologies as pestilential?

Maybe the individual galactic factions are hive minds, but what guarantees that those hive minds are in turn going to get along with each other and not just recreate individual human disagreements and pathologies on an interstellar scale? Perhaps the reason we've never picked up any transmissions from aliens is that all the hive minds have blocked each other on Interstellar Twitter for publicly thinking something offensive fifty million years ago.

Not necessarily.

Yes necessarily. You can't build an interstellar spaceship without an industrial base, and creating an industrial base is going to have the same effect on the local ecosystems that humanity is being damned for. At best, our alien hive mind is a giant hypocrite.

Not necessarily.

Starship Troopers.

This only happens because a human being's short lifespan, limited mind, and constricted point of view mans that a human's perceived self-interest is very limited in scope. A planetary scale hive mind could have a much longer lifespan and a (literally) inherently more global view.

Externalities arise because of a limited scope of knowledge, and persist because of self-interests of tiny scope. We think markets are so wonderful, because the distributed computational power of many individuals can keep up with global complexity. What if a single hive mind could command the same number of neurons, without the disparate competing self interests getting in the way?

It could presumably accomplish great tasks more efficiently without the waste of individual human beings skimming kickbacks from the interstellar spaceship budget or arguing about what color the ships should be painted, but building them is still going to require a massive industrial effort that will have a significant effect on ecosystems, no getting around that.
