Perhaps "suffer" isn't great here, because it's used coloquially as "being affected" and to literally suffer because of something. People will be affected, absolutely. And some people might also suffer from not being able to have an international vacation. But probably not reasonably so, i.e. a reasonable person would not suffer in that situation. You can suffer unreasonably, and you're right, it's irrelevant to the question of "does suffering exist", but it's very relevant to the question of "should we do something about it as society". If it's reasonable, probably. Otherwise that's between an individual and their therapist.
