So you want to abolish something but haven't given any thought to what should replace it?
The NHS was put under enormous pressure by a new and poorly-understood disease that was particularly dangerous to older people and those in poor health. Guess were these people tend to hang out?
The decisions taken about maintaining NHS services at the height of the pandemic in March and April were judgement calls and would have had to balance competing risks and trade-offs, possibly with a good dose of political interference thrown in. Whether those decisions were right will probably only become clear once the pandemic is either cured or mitigated. The NHS is a finite resource so when demand exceeds supply something has to give. If you want more capacity, then be willing to pay for it.
Other health services (Spain, France, Italy for example, the US doesn't have a health service, it has a health industry) suffered similar or worse breakdowns. For all its faults, the NHS does a reasonable job despite the
UK having one of the lowest per-capita spends across similar industrialised, high-income nations. Funding is a political decision. If you want a better health system, then vote for a government that's willing to be honest about how much that really costs.
Abolishing something doesn't make the problem go away.
