Government money does not come from taxes. It's distressing how few people understand that governments with sovereign currencies literally have a license to print the money they need. There is absolutely no need to borrow money, or even to collect it in taxes before spending it.
The ritual of borrowing is a political choice - which, incidentally, undermines democracy by giving a casting vote on policy to lenders, not voters.
It is not an economic necessity.
The proof is the way that bailouts tends to happen whenever the banking system or a critical strategic industry is on the line. For some reason this only applies to selected industries, and not others.
But inflation! No. The government can set up price controls on profiteering. But besides that, this fresh money is there to keep the economy at a steady state - specifically to avoid a black-hole depression.
Sitting by idly while most of your business base is lost on the far side of that event horizon is far more dangerous than any other risk. Especially in this case, when the lockdown is likely to be fairly short - more than three months, but certainly less than a year.
And it's not as if there are no unexplored options for other productive activity, especially in healthcare.
The real danger is the moral hazard - the political realisation that financial scarcity has always been a deliberate systemic political choice, not an inherent property of an objective financial system.
