You're implying we'd easily see megastructures. Believe it or not, there's many more stars we haven't inspected than have. And our telescopes suck too much to see all but the largest megastructures, which you're assuming it would make rational sense to build in the first place. There can be better things for an economy to spend its (always finite) resources on.

> which you're assuming it would make rational sense to build Yes I mean why not. If you are an expansionist advanced civ, travel is impractical and you have enought time and resources then what else is there to do? Obviously there are explanations "why not" (as I said), but insterstellar travel unavailability is not one of them.
