It's already surprising how much of the activity turned out to be "non-essential". And we can have oil at half-price to do the essential. :D
Worldwide, that's not to be taken for granted. Here in Russia, the police is sometimes stopping agricultural workers from planting their crops because of the lockdowns. (Source in Russian: https://www.kommersant.ru/doc/4311038)
Could you explain what kind of lockdown model you are thinking of that would prohibit production or distribution of food?
As an intentionally pessimistic estimate, to counteract all the over-optimistic estimates, I think it makes sense.
Would you prefer it as “5 years until a return to normality”?
So the headline and thesis have been successful in getting us discussing the situation, but the content is weak with no evidence from a source with zero credibility.
For me personally, just saying “prepare for a much longer lockdown” wouldn’t be better; without a concrete number it makes much less of an impact.
With a concrete number in there, even if it’s very clearly just a guesstimate with huge error bars, it makes you think about what the effects might be in the real world, which I think is helpful (in fact it’s the very point of the whole post).
