Am assuming you are not closely related to the 45000 British dead, and are not in a vulnerable demographic so such conceptual statements are easy to type away. Lucky you.
My parents are a vulnerable demo. They're in their 70s, but otherwise in good health. Wouldn't normally be expecting either of them to go anytime soon... so Covid is exactly the sort of thing that could come in and change that scenario. So I am affected.
But death is a part of life, and it is a part of society. The day each of my parents goes will be the saddest of my life. And yet I know that it will come... so I do not ask the world to alter itself deeply to lower that risk. This isn't my point, my point is just to rebuke what you said.... I say this as a person who is also affected.
As I said, death is a part of society. Which is why on one level we count it in order to track if we're seeing increasing death or reducing death. As you can imagine, long term death trends in developed countries have largely been falling, and that is good. The death rate in many places hovers between 0.8% and 1.0%. But that still means that in a country with 330 million people like the US almost 3 million people die each year. And yet we are not alarmed by the number itself.
The worst of covid-19 in my opinion was around the late March/early April timeline for the European countries hit hard, and the US east coast. Death was occurring at between 2x-3x the normal rate. So basically if you go for an entire year like that in the US it would mean 6-9 million deaths.... not anywhere close to acceptable. So an aggressive public response to that seems entirely justified. But having navigated that difficult phase, in several countries the death rates has moved back to being very inline with the normal, in some cases even lower. Source:

It obviously won't stay like that if everything goes back to normal, so vigilance is required. But there must be some balance between the protection of life itself x the protection of other aspects of life. I don't question the public health and medicine experts about the aspects of the virus and its potential for destruction. But let me then speak as a partial expert on something else: except for countries in the process of being defeated at war (like Germany 1918 or 1940s), I do not remember a more aggressive and more targeted reduction of economic activity in modern history. Society already underwent deep strain in so many places in the 1930s because of the Great Depression. In countries with weaker democracies it was a key ingredient in the fall of democracy itself.
I do not know if it is possible to get out of this situation easily. I worry that governments are not supporting affected sectors and workers enough, and yet I worry that the size of what support that is being given will be unbearable for the public finances of some countries. We already traditionally struggle as societies to manage the downfall of certain industries that occur over decades, usually leaving parts of the country those industries were concentrated in in bad shape for decades (think Detroit auto industry, UK coal mining). Yet right now we are going through the same thing on a wider base, at an accelerated pace. Forget shareholders/banks (even though that stuff still matters), but think of the fact that we have for years signaled to people that being a trained airline pilot, flight attendant, aircraft mechanic, dispatcher, etc was something that we needed in society so it was a path to an income. And now we're taking all those people that number millions around the world and saying that we don't need them anymore. They are now untrained labor in things that they have no expertise in doing. Multiply that across several other industries.
Part of this was inevitable. I know that people aren't taking flights just because the government won't let them go to certain places. The economy was bound to take a deep hit anyway. The economic argument just seems like I'm trying to protect money over people, but its not. Our economic organization is the means by which we make and allocate basic things like food and shelter. We can't reorganize it for a new reality in just a day or even a year. It affects life and death too. What's more, the argument about the economy came from dipshits who didn't understand that a big hit was coming anyway, and were (and still are) just trying to win the US election. They don't care about any of what I'm saying (I'm not sure they even understand it). But I'm trying to make a more thought out explanation of why it still matters.
This is a mess of a post so I'll just try and wrap it up by saying: in considering continuous measures to reduce the deaths by covid-19, it is still necessary in my opinion to balance the other costs of the actions. Death numbers will count into the tens of thousands anyway, because our societies already face death at that rate on a weekly/monthly basis (depending on the size of the population). But if you keep it in proportion (in my opinion best measure is excess deaths as a percentage) then you're also better able to balance it vs another proportion that is arguably a lesser impact but are affecting millions, and also has the long-term potential to cause death and destruction.
