That article is not well written. The failed premise is to treat the US as one entity, or region. Everyone knows at this point that regions and states will be on their own curves, depending on when the virus appeared to grow exponentially, and the success/adherence of mitigation strategies (social distancing, no gatherings, really staying at home not faking it).
New York, as an example, is on a downward trend in new hospitalizations, net hospitalizations, and fatalities. They're on the decline of their full first curve, which can take roughly 56-77 days based on other countries. The curve is bell shaped, but the declining slope is less steep than the inclining slope. It's tough.
If regions try to re-open before they are on the downside of their curve, then they're not being patient enough/prudent with the data, simple fact. If New York can come down off of high death tolls of 750-780 per day to now being under 300 for a few days in a row, then anyplace can do it. It takes discipline and patience, unfortunately neither of which seem to be ruling the day in a lot of places. You can't just skip the steps. "Oh, we stayed home though." Really? Or did you pretend. The data doesn't lie.
