If transmission on the air plane is the risk you worry about, I agree that it doesn't appear that different compared to other risks associated with going outside.

However, travel obviously takes you to a new place, where the every day risks might be much greater or at least less well known than the ones you have to accept by virtue of just staying alive where you live.

Further, you also have the risk of being stranded due to local outbreaks closing borders at some point during your trip, making the duration of the trip itself uncertain. Not many people take lightly the risk of not knowing when they can get home from their vacation.
