why build starships

[Rusty_Nail]

I meant starbase,not starship, and it is not cloaked and uses long range weapons. But I do not feel you understand my question. If an incoming ship is programmed to not attack a starbase (and why should it after all, when the starbase can be bypassed, just like a satellite?), than it would seem to perform no useful purpose. I have tested this. They are simply and easily ignored while the fleet takes on other ships and the planet. I can see only one use, and that is to build a ringworld, unless I have missed something. Maybe the problem is that most people have not discovered that you can avoid attacking them in strategic combat. Could that be?
