I think that rather than "punitive" measures, there should be a more sophisticated understanding of why the virus continues to spread in certain areas.
It's known that there is a higher density of cases in areas where there are high levels of deprivation and poor housing. There is a higher percentage of people in such areas doing zero hours jobs and other jobs which can't be done from home. Many of them don't pay sick leave, so people carry on working. They're also likely to live in housing and have caring responsibilities, which make self-isolation difficult.
For example, one poor area of Liverpool has a very low (4%) uptake of free testing. The reasons being given are that people don't want to know if they're infected because they wouldn't be able to work.
Ethical question - how do you feel about second chance??
