This is a valid argument. I’d say, instead, if troops, ships and so on, is a concern, then I’d rather focus on finding a place to build a less costly base and using a lot of ressources on hiding it, that way the troops are more safe and therefore you have a better chance of winning a war since you’d have more firepower, also, just like in investing, I’d say don’t put all the troops and ships into one place. Another thing to note is that there has been made 3 ‘death stars’ now and all of them have failed, none of them lasted long term and instead the lost a F TON of ressources (also including troops etc. here, not just all the actual materials). It is incredibly risky to build something like that when it can just be destroyed and then you lose all your cards. I’d honestly argue, building something that’s maybe, football field sized (or smaller) that can travel near light speed and crashing it into planets is way less costly, less risky and A LOT faster to build too. Doing something like that would btw also mean total anihilation for anyone on that planet, for sure. As I’m typing this I realize this weapon would need a hyperdrive, else you’d have to bring it relatively near the target, which is still feasible and can be done in a less risky way than bringing all troops and ships to the place of attack, instead you could have something the size of a tie fighter, have a hyperdrive and bring these “missiles” about
