Great. Tell legislatures to (a) act faster when there's an emergency, or (b) enact better safety nets that automatically kick in when an emergency arises.

The fact that central banks can act quickly isn't a sign that what they're doing is wrong on the monetary side, but rather that the fiscal side of things needs to get its act together.

It obviously belongs there because anything else would fail to create the desired level of inflation as we can see today. What we truly need is fiscal policy and it's funny how on point this 8 year old cartoon is:

There are other ways to inject money into people's pocket directly by reducing logistic cost by investing in better infrastructure. Everyone from top to bottom uses roads and railroads, airports, seat ports for shipping. Everyone benefits from having them fast and more efficient.

Yes, longer term. A new road doesn't help you today when you have to choose between paying the mortgage and buying groceries. Giving money directly to banks to cover their liquidity while people get thrown out of their homes because they can't pay their mortgages with the same banks is monumentally stupid and I don't give the people who made this decision the benefit of the doubt. If they are that stupid they are not qualified to be in their jobs.
