As the originator of this topic, I wholly concur with Mr. Wolf's immediate thought.
With reported COVID cases at half that from a year earlier, and with nothing to suggest that the post 2021THANX Omicron "spike" is presently about to occur, we as society must accept that COVID "is something we live with" just as we do seasonal influenza.
There are readably and available safe, effective VAXs for each. While there are segments of the population, largely owing to religious convictions, that choose not to participate, but for the rest of us, life will go on although however changed.
The change largely is how we work if we are classified as a knowledge worker, as distinct from front line. Society as a whole, needs to accept that these changes are permanent and so for what we gather here to discuss - passenger railroad transportation and the adverse effect upon such, we have drawn the conclusion that "it's never coming back".
All parties in interest had best accept such.
