Just a detail to consider.
I've been traveling a lot lately, mostly by car, but I just finished a couple of flights for the first time in a while. Both flights were around two hours each (domestic travel) and I was intrigued to see that in both airports and both planes, hardly anyone had a mask on. Considerably less than 1% of all the people I saw. And even the few who did wear a mask often wore it in a completely useless configuration (nose exposed, even just as a chinstrap).
So while I can understand why some still do this (immune issues, general nervousness, etc.) and I definitely don't think it's silly (for them), you should be aware of what you'll encounter.
I flew roundtrip from DC to Paris last Sept/Oct. Two unmasked friends of mine contracted Covid flying home on transatlantic flights a few months before my trip, and another has since contracted Covid on an international flight to Latin America. I asked one of my friends whose symptoms began a few days after getting home, whether she masked on her flights. Her non-response was "Nobody masks in Europe."
My flights were full, and going over, about 25% of passengers were masked, and about 30% were masked on my flight home. Some flight attendants on both flights were masked, too. I haven't been on any domestic flights, so I have no first-hand knowledge relating to the 1% figure you cited for masking.
I only removed my mask to briefly eat or drink from the moment I entered one airport to the moment I exited the arrival airport, about 13 hours despite nonstop flights of 7 1/2 and 8 1/2 hours actual flight time. Long waits for boarding, deplaning, and a very long wait to go thru immigration in Paris in a hall packed with more than 1,000 people. I also masked when I was on the Paris Metro and other trains. I'd estimate only about 10%-20% of other passengers masked on Metro or other trains. But I ate dinners in restaurants every night. I had no intention of spending 3 weeks in France and avoiding restaurants, but I did avoid bars and crowded indoor cafes, though I usually avoid them anyway. For most of my trip I was in the French countryside, but I spent 5 days in Paris. New case rates were quite high in France during my trip.
I did not contract Covid. I'm sure that some luck was involved. I don't have "immune issues" or "general nervousness" (AFAIK), but I believe I was simply being prudent. I wanted to maximize the likelihood of remaining healthy and enjoying a much-needed break from dealing with eldercare matters back home. I had a great trip.
My advice for travel is to do whatever you think is prudent, regardless of what people around you are doing.
