A relevant factor for countries that have largely controlled covid, or back in March when it was uncertain what direction which countries were going in. For ones that have just let it rip though, the people who were going to get it from you are just going to get it from someone else if you isolate.

If I as an Australian have covid and go to a gym and infect a bunch of people, I've given covid to people who otherwise wouldn't have caught it. If an American does the same, they've given covid to people who would have just caught it next week or next month. They've also given it to less people because a lot more people in that gym have already had it than in my Australian one.
