I don't think it is that simple. I think the UK (government, public health and population) has given up any belief in eradication and is now full steam ahead for endemic. There's an assumption that we'll all be exposed to the virus (now, next month, next year) and we'll either be vaxxed or unvaxxed when we catch it.
The only real difference between the approaches being suggested by most of the key scientists relate to mitigation, not to principle. Mitigation matters most if you can vaccinate more people, or if you have a better vaccine or better treatments coming through, so you can buy time to save lives.
Which is where the arguments are focused: wait for boosters? Wait for under U16s? Wait for vaccine passports to kick in? The English (even more than the UK as a whole) are currently assuming that the U16s will be ok, and that those at risk will either stay home or get a vaccine/booster. Meanwhile, the more people who catch covid now, the fewer immune naive people there will be to infect later this winter.
Grim as it might sound, the assumption is that the bulk of hospitalisations/deaths can only be delayed (aka the curve flattened) not avoided. In this model, only testing (before you go to work, visit granny, get on a bus) is useful on the mitigation side - as it may help other people avoid risks.
It is absolutely brutal for the immune compromised, those who can't take the vaccine, those who got too scared/over-confident to take a vaccine, and those who got vaccinated but are still unlucky.
It's also not great for the rest of us, who maybe can't get routine medical treatment. It must be painful and exhausting for the medical and care staff trying to cope. But does a longer, slower battle really do that much to change that? That's the great unknown, and I really do think it's an unknown at this stage.
TLDR: not just about money.
I think boosters are a bit of a plot twist. If they ramp up efficacy to a level which will see cases squashed to a very low level (as well as enhanced protection for elderly/vulnerable) then that’s a rationale for buying more time with mitigation. Early data out of Israel about efficacy of boosters is impressive.
