Here's my thoughts on the UK government's position. For clarity, I make the assumptions that covid19 has R0 = 2.5, 20% of cases need hospitalisation and 1% die

If no-one was doing anything differently, the R0 of 2.5 implies that the number of cases will increase until 60% have had the disease and are immune. At this point, there is herd immunity [this is (R0-1/R0) - 1.5/2.5 = 0.6]
