The age-stratified IFR is magnitudes different between people under 40 and people above 70. You can still achieve herd immunity without infecting the vulnerable.
We have become better at treating patients with time as well, we now know that putting people on ventilators is a phenomenally bad idea, oxygen, steroids, and blood thinners is the way to go.
Also, the death rate in the US is higher than in Sweden, so how are those lockdowns working out for you?

If we take that into account then California actually has more deaths per capita than Sweden, and people are still dying in California so it will only get worse. So I agree their strategy was not all that good.
Is Sweden comparable to the US? The population is more like a US state. Let's take Oregon as an example. About half the population of Sweden, and less than 10% of the covid deaths. We're not exactly locked down, either.
Massachusetts, Connecticut, and Rhode Island all have a total covid-19 death rate that's more than 2x that of Sweden.
Currently, the average daily cases is 5x higher in Rhode Island than in Sweden, 3x higher in Connecticut than in Sweden, and 2x higher in Massachusetts than in Sweden. The current daily covid-19 death rate in both Massachusetts and Rhode Island is higher than in Sweden.
great, but what's the point? That Sweden is doing better than about a third of the United States?
The original point being made is that it's apples to oranges to compare the U.S. as a country to another country that it dwarfs in every population metric if you're looking at how to shape public policy.
In other words : There doesn't seem to be a one-size-fits-all solution for nation-wide policy making regarding a pandemic that fits every culture in the world.
I don't think that this surprises anyone.
