The article's answer to this question is "the eventuality of endemic COVID-19 does not mean we should drop all precautions. The more we can flatten the curve now, the less hospitals will become overwhelmed". There are currently ~6000 COVID patients in hospital, which is a little less than 1/6 of the Jan 2021 peak and over 1/4 of the April 2020 peak. Which is to say, manageable right now but probably not something you want to let burn much hotter than that.
