I guess my point is: By the time we’d be able to travel that far, we’d have the ability to make all such observations without showing up on the planet.
Though on the other side of the coin, if interstellar travel were so ubiquitous, who’s to say all aliens would behave in such hands-off ways? Maybe any aliens that would visit Earth would be the equivalent to rednecks driving out in to the woods to shoot squirrels. Or in a more innocuous analogy, bird watching without binoculars.
No, it’s really not that way, unless you’re a guilt-by-association simplifying dolt. One can be a communist and not like how China is ran nor have to defend it.
