If no country has ever achieved this, what's even the evidence that it's actually possible? There are some pretty fundamental reasons to think it wouldn't work, not least of which are asymptomatic, pre-symptomatic and barely symptomatic spread, and the fairly impressive R0 of this particular disease. If the person you're having dinner with doesn't have symptoms and you have a slight sniffle, how do you even know to get tested?
Also, how the amount of coronavirus testing the US is doing stacks up to other countries isn't an "particular opinion" - it's a fact, and it's a fact that pretty much the entire US press seems to have managed to misinform everyone about, including the fact check columns.
