It is far too early to be calling that a failure.
You don’t get to rob people of their basic human rights. Ever. That is why they are called “human rights”. It means you don’t get to take them away.
Pretty much every country on earth disagrees with such a binary statement, unless you can point me to one that doesn't have prisons.
(I'm not saying prisons are wonderful or arguing for/against them here, nor saying that everyone in each country agrees with the current policies, just pointing out that all of our countries have laws that say you DO get to rob people of their basic human rights in certain situations.)
That is a bad argument with no bearing on the current situation.
As the virus has mutated the strategy to deal with the virus needs to change. Early on China's strategy was effective at preventing deaths (the costs to achieve this could be debated), but now the virus has changed and that strategy is proving to be a terrible one with a massive cost to the country and their population. The significantly higher transmissibility means that spread cannot be prevented (only controlled) and the availability of vaccines means that deaths are far less common now.

The Economist "model" your article relies on is seriously, seriously flawed. It is laughable to see it reported on as if it is ground truth. I highly encourage you to look into the details of how they get the numbers your article is citing.
If they'd already been hammered by coronavirus and covered it up, then they'd have high levels of natural immunity and wouldn't need to be pursuing this zero covid policy.
Any what exactly do you think the end outcome will be when a) it is impossible to stop omicron and b) the CCP isn't ramping up the vaccination effort on the 80+ yr olds?
If live in a tinderbox with frequent lightening strikes, spending billions on firefighting isn't going to change the end result. HK got to 1/3 the US's death rate in __weeks__.
Even that wouldn't work, there are covid reservoirs among wild animals now (e.g. deer).
