I honestly don't think our Govt. - or any govt. for that matter - seriously expects the 12/14 weeks quarantine to be maintained. My hunch is they're hoping for something like 2 weeks before everyone starts 'breaking out'. Much better than telling people it's going to be 2 weeks and then seeing people on the streets after 2/3 days.
If I'm wrong and the timescales are accurate, there won't be anything left to return to - jobs, business, economy, nothing..
