Laughable (again).
You think that authoritarianism and intervention are one and the same thing and you'd risk thousands more dying to avoid being more vigilant and interventionist.
Dave, I appreciate you see this is serious and want action, but many thousands are going to die regardless of what actions the government take.
It should now be apparent that this is a highly communicable virus and it's already circulating within our society. If the government declared martial law, shut every border and suspended each and every civil right we had tomorrow and said that anyone breaking curfew could be shot on sight then many thousands would still die.
Politics is the art of the possible. It's possible that effective actions by the government can help to reduce this, can help our systems to cope. It's important not to overstate this, it's not the end of the world, but when they tell you that they're aiming by their actions to reduce the deaths by 20% to 30% then that should tell you that they recognise and want you to recognise that we are in for a very tough period.
At some point they will do the same thing that Italy has done, experts will be looking at the optimum time to do this. Social distancing will help slow the spread, but the spread will still happen, just hopefully over a longer period. It can't be sustained indefinitely either and if it's implemented too soon it will destroy the credibility of the experts who we will need to listen to over the long haul.
