Just ignoring those who die is one option, however long covid is a thing. A huge portion of those who get covid are still very sick a long time later. A majority have symptoms 6 months later, and some are very significant and life changing. This needs to be considered when suggesting letting the disease run rampant.
You may actually be limiting lives more by not locking down.
My view is very coloured by living in New Zealand where aggressive lockdown has lead to normality (with limited international travel and mandatory managed isolation).
