It's still within our power to eradicate the virus. And, again, with the narrow focus on deaths. Not everybody who "recovers" from the virus is really better, and it's already been understood that many survivors suffer from severe long-term problems that are, if anything, worse by virtue of being prolonged suffering.
There are approximately three realistic scenarios for the rest of the year:
1. The rise in serious cases and deaths soon peters out, and we're left with what I would assume is the scenario you are envisaging, whereby maybe 10,000-15,000 die from Covid in the UK for the rest of year. This is clearly tragic, but is also an inevitable part of life, and in this event we can be thankful as a society for small mercies.
2. The rise continues, but the vaccine defences hold firm enough that, although far more people die than are necessary, it's also still "only" 30,000-odd across five months, and again a price worth paying for a functional society.
3. A vaccine-resistant variant emerges, and we are once again facing huge daily death tolls and packed hospitals for a sustained period. Facing an absolute bloodbath (for, without social distancing measures in place, flu is also free to spread), the Government is forced to bring back serious controls in the face of a wave that resembles the first peak.
Take your pick with of the three is more likely. I'm inclined towards (2) at the moment, representing an average of 200 daily deaths at most over the next five months. It's worth bearing in mind that we are already averaging around 50 a day and increasing, and, while, yes, that is small at the moment, if the last year has taught us anything it should be the meaning of exponential growth.
And this still leaves unaddressed the long-term damage to many tens of thousands more. The problem with the " we will have to live with it" approach is that many won't.
