Buying flight tickets might be cheap right now but the point is if when your trip starts X weeks from now and the situation is still bad and you don't cancel it, then you are indeed selfish and deserving of the negative comments and down votes.
Further, since nobody knows when this will end (it could continue into 2021 for all we know) and you didn't say you'd cancel your plans if it did (instead you expressed concerns you'd lose money if travel was banned), I feel like you're drastically misunderstanding the 2nd order dangers your actions would have and likely deserve the ire and down votes you're getting.
That is the risk I referred to, as I clarified—not being able to take the trip because the situation didn't improve. I've explained this many times over by now.
To travel after the trouble with the virus has subsided on tickets purchased during a period of discounted rates?
Or do you mean not traveling because the virus hasn't subsided and tossing the hundreds of dollars down the drain in a gamble?
If neither of these were your conclusions, then respectfully—I think you misunderstood my comments.
