> Americans [...] have replied that they don't want to quarantine because it would ruin their holiday. The average American vacation lasts for 17 days[1]. A 14 day quarantine would absolutely ruin that.

If there's one thing Covid-19 has demonstrated, asking people to do the right thing fails in aggregate. If a country doesn't want tourists breaking quarantine, they're going to need to mandate it.
