I most definitely do not want to endorse the UK's strategy, but your summary of it does not seem accurate.

In what way?

It seems very likely that immunity will last nearly forever in survivors

Where are you getting that?

The UK strategy seems to me like a bet that they can isolate susceptible populations (mainly old folks) from less susceptible until heard immunity develops

The study you linked was testing for re-infection immediately after recovery. I don't know why you would assume that equates to lifelong immunity, especially when immunity for other coronaviruses wanes within a few months to a few years.

The relevant time scale here is days, not months/years. Flattening the curve means going down from 20-40% increases per day.
