Again, i would ask for clarity -
The government spent £600 billion over covid. My 3 person family does not have an extra £45k in the bank, so where has that money gone?
Its a simple question.
And sadly a flawed question...
It is not as simple as saying that £600B spent is somehow distributed as £600B extra sitting in bank accounts... it wasn't barrow loads of cash handed around...
You only have to consider the high number of people who worked before covid but were then furloughed to realise where a lot of money went - those people won't be seeing extra money in the bank because in effect they have already traded it for not working, so they have had their extra in the form of paid holiday - that was an estimated £60-70B handed out as free cash to allow people to not work - very nice for those who got it... and let's be clear, that was mainly to those who are at lower ends of income.
Not sure where you get your headline £600B figure from - the National Audit Office lists it as £376B:
£147B support for businesses - difficult to quantify who benefited, there are certainly a number of fraud cases in there, but most of this will have been to keep businesses running - and much of that money ends up with employees being paid (e.g. the hospitality businesses)
£89B for health care
£75B for public services and emergency responses
£60B for individuals (e.g. furlough)
£5B for other support etc.
Costs vary from supply of more medical equipment to propping up businesses -> investing to then reduce backlog as we come out of covid (e.g. backed up court cases etc.)
it would be wrong to see it as simplistically as x was spent where is my share - I have no idea of your personal circumstances, e.g. whether you were furloughed etc. - if you were, then that is where your share went, if not, then in the balance of how government works you helped others so that we could have the best possible exit from Covid with businesses and services still running - and to keep that going when basically normal money has stopped circulating is very expensive...

regarding your other points on taxation - I think that
@deema is very perceptive in the comments being made... I understand your belief that everything comes back to something tangible, but...
a) it really doesn't - there are plenty of examples of bubbles (from the Tulip bubble of the 1600s to the South Sea Bubble to modern crypto bubbles) to realise that you can see wealth being created and destroyed with nothing tangible behind it.
b) the biggest issue is that the taxation powers of authorities doesn't match the patterns their 'subjects' can deploy - the simplest being geography - If I set up a business abroad, and use that as a shell to transact - who gets to tax it? I could be 'poor' in this country - but wealthy on an international basis - e.g. Philip Green who famously owned very little in the UK - his wife, domiciled abroad owned it. I can still enjoy the lifestyle - my 'abroad' company can buy a jet and I can use it to fly me around the world - it can buy me clothes / jewellery / stays in nice hotels / great holidays / expensive boats and cars - yet none of it taxable in the UK. I can fly my car into the UK and drive it here, with zero taxes (other than petrol) - if the car is in the UK for less than 6 months a year I can run it on foreign number plates and it needs no taxing or registration.
So, for the wealthy (who do own a disproportionate amount of the world's wealth) they get to choose where their money will be taxed and where it will be used, and the two do not need to be the same. There will always be a country happy to give the uber wealthy residence - the rules for the wealthy are different.
So, ideally you want our country to be the place where that wealth resides - as then more is spent there and you are taxing (albeit at a lower rate) from a vastly larger pot, which is still more than otherwise. That means being a country of low taxation. And yes that might arguably help the richer people, but they are the ones with alternatives who will help themselves anyway, so it is about setting up an approach which ultimately helps the poorer and high taxation does not help the poor.
Low taxation can make it tricky to balance the books - but a big part of that is to do with spending, not taxation. The media and commentators get it wrong when they keep commenting (e.g. about the Truss budget) that it is unfunded cuts - actually, you can't have an unfunded cut in taxes as you are simply not taking money off people, so it is totally funded as they already have the money and simply keep it - the issue in balancing the books when lowering tax is that you end up with unfunded spending - therefore the big issue is actually government spending, not taxes and that is something the government needs to tackle - we live in an era of ridiculous costs of spending - numbers of civil servants / HS2 / etc.
Ultimately the ideal is low tax - encourage the wealthy in - and then compassion towards those at the poorer end - with a more rigorous understanding of whether they should or should not be getting support (ie try to tackle the abuse of the benefits system)...
We also need to re-visit what actually is essential and what is not - as is noted above, our minimum standards of living are vastly different now to what they used to be - but we can perhaps challenge some of them - it is not necessary if you are struggling to feed your children to have a car, or an expensive computer / phone as priorities - we need to resource public transport and local access to the internet so that there are free or cheap options. We need to re-visit the housing market and the balance of types of properties from shared ownership to council, private to rented etc.
