MMT is a good strategy to enhance the economic system, but it is very risky to implement it in s situation like this. We might be looking at the 6th global crisis now. To major stabilizing factor in the MMT system is taxation, and while the pandemic is going on and a lot of restrictions apply, people keep losing their businesses, taking loans from the banks to keep living the worst thing that can happen is the governments increasing taxes, while people won't have enough funds to maintain their lives. This would only mean less income, more debts, more loans, mortgages..you see where this is going. This can turn very nasty.
