Some people have adventures and others have “in-ventures”. You are ok with holing up in your abode for years of your life to avoid a mild risk (assuming you are under 70 years old and reasonably healthy). Others are not willing to live this way and would like the freedom to make that choice. Some people, by the way, have less choice, like the people that deliver your food and merchandise to the cave you call home or the people that treat your non-covid (of course) injuries and ailments.
