Death is not the only metric that has an economic impact, that is the point.
Yes, COVID is by far less deadly now than it was in the beginning, thanks to vaccines, medication and treatment knowledge. Nevertheless: When hundreds of thousands of people, especially in industries that make close contact with random people necessary such as healthcare, hospitality and public transport, get sick for weeks, the economy still suffers.
Or, to use a pun I'd hoped to be able to avoid, but the opportunity is too good: How can we move on from the pandemic when public transport literally [1] doesn't move? How are people supposed to go to work when entire train grid cells are not working because the signalling controllers all have COVID?
