That is great however from eye witness reports all travelers do not think like you do. With the lack of required testing to return home for US travelers I agree with the comment above...they will not be as careful and many more will be on the planes with Covid. Just the facts. High season is kicking in, pent up travel demand and you can expect airports/ships/trains/planes etc. all to be packed. I think it will be difficult for cruise lines to enforce masking onboard when basically the rest of the travel world is ignoring it. You just have to be up for the challenge or not take vacations where you are guaranteed to be around lots of people. Right now cruises are a high risk venture for covid.
