All the outcomes I've seen that reach herd immunity involve an unacceptable amount of harm - both in deaths to at risk groups and in terms of suffering across the board.

While we may have to face this outcome I think it's too early to do so until we have more data and a deeper understanding of the disease.

In the UK I get the impression that the population is more cautious about loosening the lock down than the government is. I think other countries are the same. The US might be the outlier here.
