Apologies for quoting myself, but it looks like this is actually the plan, and not just a 'theory', i.e. to 'allow the disease to move through the population'. Otherwise Sir Patrick Vallance, the chief science adviser, wouldn't be talking about 'herd immunity':
https://www.bbc.co.uk/news/uk-51865915. As there's no vaccine yet (the usual way to bring about herd immunity), it's achieved when enough of a population
contract, survive and become immune to the virus to lower substantially the chances of contagion. Of course, many will fall at the first hurdle. In any case, not enough is yet known about the virus to say whether herd immunity is even achievable this way: this coronavirus is reckoned to be seasonal, and that means it could develop strains that require new vaccines.
