Its a great question. And I am not sure there is any clear answer at this point in time. What we can look at is past epidemics as well as the seasonal flu for comparable metrics. In reality the total deaths would be only be able to be tallied once the population has a 80% immunity to the virus either by natural or by immunization. When it comes to natural immunity the only impact on the total deaths be it all at once at the front or spread over a couple of years is the small fraction that could have been saved in a worse case scenario where the medical community is overwhelmed and those who could have been saved are not treated. We will never know what the true number of those who would have perished with out medical intervention some published papers are putting it at a tenth of a percent. So we go from 2.7% to 2.6% but its hard to know who would have lived or died without medical treatment.Just on your upfront deaths theorem, the UK had a significant number of upfront deaths in March. Now it's having an even bigger spike in deaths now (BBC graph screenshot below)... front loading doesn't seem to have done anything between 2020 and 2021 - When exactly are we going to see the positive results of it? In one year? Two years? Five? Maybe ten? If it's ten, the population isn't getting any younger and you'll have a whole new generation ageing into the most vulnerable groups before you see the benefit of letting the previous generations elderly and frail die early:

And come to think about it, what exactly would the benefit of front loading look like anyway? After the first wave in the UK the death rate in August just went back to the average, it didn't dip down in a trough of all the people who would have died soon anyway... what should we be looking out for as the benefit of all those dead early on in the pandemic?
The other and by far biggest impact on total deaths due to Covid-19 is immunization. While immunization is not 100% and in fact there will be some deaths due to complications from the process it has the potential of reducing the current projected death by over half. Of course this relies on the immunity being highly effective in both targeting the current strain as well as the prompt distribution of the vaccine. And that comes to the crux of the dilemma as we are already seeing variants that are reducing the current vaccine from 80% effectiveness to less then 30% effectiveness and we have only just started rolling out the vaccine to a few million individuals and a year end coverage projected at less then 20% if manufacturing, distribution and administering holds to their planed rollout.
So how many more years of partial lockdown do we subjugate ourselves to?
What is interesting about virus mutations with in a species is they typically do not get more sever only more infectious, and often times their severity goes down. The added bonus is those who survive the virus have the antibodies to reduce the severity on future infections.Of course, to have upfront deaths you need to have the virus spread around. And the more it spreads, the more chance it has to mutate. Would there be a UK/SouthAfrica/Brazil set of variants which may be less effected by vaccines now if we had all done a New Zealand and got a hold of it early on and kept a lid on it? No one can say for certain but I'm sure those chances would have been a lot lot lower.
If only this were true. Unfortunately Covid has always been zoonotic and while it might be possible to eradicate it in the human population in a month (would need to make sure enough time for worse case scenarios of slow transmission between family members) it would still jump back to us from infected animals. What is worse is because its zoonotic when when it gets introduced back into animal populations it has a significant higher chance of acquiring new skills and generating a new novel virus like the strain of Covid that we are currently dealing with.For the most part if everyone on the planet stocked up with two weeks of provisions then shut our doors and sat it out, everyones immune systems would do their thing, the virus would be killed or kill, and that would be that. No more transmission, no more unprotected subjects to incubate in. Vaccinate key supply chain people to keep bits and bobs moving, and lock down the world for 14 days. Would it be difficult. Hell yeah. Would it bankrupt the world? Heck no just put everyone on a bills/mortgage/etc pause.
The world could put its feet up for two weeks and let biology do its job. Would it get rid of the virus entirely? Probably not, but it would get it down to a level the world would then be able to keep control of it. Won't happen though, the population doesn't have the desire or the imagination to suffer a short term to benefit a long term.
And you know how long it would take for the world to rid itself of COVID-19?
14 days.
