After the press conference, Danish TV had some commentary on this, because of course they did.
One of them, a medical professional, said that there's only really one number that matters for this plan: How many people are going to need hospital treatment?
If you get the virus, but can stay home and feel mildly awful for a couple of weeks, you're essentially handled from a government point of view. Stay isolated, don't infect others, and you'll handle things on your own. So economically and from a medical point of view the number of mild infections is mostly irrelevant. The important bit is that if you show cold or flu symptoms, you STAY HOME. If it's actually corona or not doesn't really matter unless you need a hospital now. Stay away, get better.
And for what it was worth, he was actually quite optimistic about the whole thing now. We're doing the right things, if we actively try to reduce infections, retool the hospitals to handle more of them, and slow everything down, we'll beat it. Not without deaths, unfortunately, but with as few as possible.
