That governments around the world will be forced to distribute "helicopter money" to keep their people fed and housed and their economies from imploding is already a given. Closing all non-essential businesses and gatherings will crimp the livelihood of millions of households and small businesses that lack the financial resources to survive weeks without any revenues.
The only question is whether governments which can borrow or print fresh currency will get ahead of the implosion or fall behind, creating a binary choice: go big now or go home.
Half-measures in helicopter money work about as well as half-measures in quarantine, i.e. they fail to achieve the intended objectives. Dribbling out modest low-interest loans is a half-measure, as is cutting payroll taxes. Neither measure will help employees or small businesses whose income has fallen below the minimum needed to pay essential bills: rent, food, utilities, etc.
