The logical conclusion of freedom is absolute, unrestricted power, yes, but even in Gallente space, hell, even out in the Nullsec sovereignties and the wilder domains in the Wormhole systems, that logical conclusion is rarely, if ever, reached. Furthermore, even if power is freedom, as you suggest, the exercise of power is still optional.
Even with that aside, the Drones have a redeeming quality. Unlike we Capsuleers, they don’t destroy for idealistic or emotional reasons. By and large, what they destroy, they destroy for purely logical reasons… grinding things down into components, yes, without any regard for what those things are, but for the purpose of building something new.
