Great point - but - shutting down the economy is not a 'conservative' policy, it's up there with 'extreme risk'.

Many sectors will crumble, it will ripple through the economy like dominos, credit dries up, investment halts, you get into an economic death spiral. There's very real possibility existential meltdown which will indirectly cause a lot of pain and death.

So 'lockdown' is 'conservative' from the viral perspective, from any other perspective, it's 'very risky'.
