Exactly. This week Germany and Portugal both shut down neighbourhoods again due to rising R0 (and if you have low cases, then 'new' cases in clusters like meat facilities make the R0 seem really high, but in the reality overall figures are still good) That is exactly what was supposed to happen with the plan that much of Europe had in place. Yet many take that as a sign that things are very bad. No, they are being controlled with testing, contact tracing, local shutdowns, etc.The goal of the quarantine is really to buy time to establish a testing infrastructure so they can do targeted quarantine, and build surge hospital capacity to handle the increase in cases when the economy opens back up.
It was already beyond containment and the economy cannot be shut down indefinitely. So you do the best you can and adapt. Mainland states opening back up and then shutting down again partially is a normal response.
Interestingly, Portugal has one of the lowest ICU per capita rates in Europe. (4 per 100,000 vs US in total 29 per 100,000) I'm not sure how it compares to Hawaii, but they managed to weather this quite well by imposing lock downs, delivering food to the vulnerable, offering free health care to illegal immigrants, and closing borders with Spain. They've shown how a relatively 'poor' country dependent on tourism could develop a way to control this in the short term, whilst opening up their critical tourism economy and even opening up more than most of the rest of Europe and earlier.
Hopefully in Hawaii during this period they were developing a plan of how to manage increases, find additional medical resources, ICU beds, etc just in case they are needed.
