totally ok with letting them get stuck abroad. It's weird that everyone is freaking out about people travelling when the airports remain open and the guidance is totally about what ppl do inside the country. If you must keep the airport open(IMO should close them), let people leave and don't let them come back. If they leave, it's their problem (and unfortunately, some other country's). Stay at home.
There are risks to traveling internationally, especially during a global pandemic. Getting stranded at your destination happens to be one of them.
I know a woman who traveled from the US to Trinidad last February to care for her mother. She is still stuck there today. Fortunately, she has internet and an understanding employer.
