@Grot I should've said adjusted for differences in population. Sweden has double the population of Norway, but ten times the numbers of COVID-19 related deaths.

I'm not sure that's the 'right' plan, I don't think there is any. Immunity has been questioned as well, since individuals have been tested positive twice. Whether that means you can contract the virus more than once, or whether those are just false positives remains to be seen. But I wouldn't assume either way without knowing it for certain. Medical research is conducted 24/7, and if a lockdown can give them enough time to learn enough about the virus, then so be it. What's the saying? It's better to be safe than sorry?

''and the reality is it’s no worse than a common cold for the vast majority of the people who contract it.'' Maybe for a decent chunk of the population, but tell that everyone who is in IC right now on a ventilator. In The Netherlands, out of the 35,000 people tested positive, around 10,000 required hospitalisation. Not everyone is tested of course, but the number of people required care isn't trivial. If hospitals can't keep up with the demand, people can't get the care they require.

Additionally, the government is providing support to small businesses and self-employed people at the moment; and as of right now it's working. Hospital admissions are decreasing in our country, and they are looking at ways to open up the country more (not right now, but in a month or so), whilst keeping the hospital admissions down.
