Let me say this slowly.
The purpose of lockdown was not to eradicate the disease. That ship has sailed.
The purpose was to buy enough time to get measures in place and bring it down to a managable level.
It was to ensure healthcare in other non-covid-19 areas was still available for all the fit and healthy people unlikely to get a serious case of covid-19 but might for example fall off their wall whilst clapping or have a car accident.
The side effect of letting the virus run unchecked would have meant there would be no healthcare for anyone. There would also have been huge numbers of people off sick with minor cases, which ran the risk of endangering the population through ways such as a lack of workers for the food supply/production chain or in running a nuclear power plant safely or running drug manufacting production lines. Lockdown has slowed the spread down and means that things can continue to run.
The whole point of lockdown was to build capacity in treatment, testing and going forward tracking of the spread of the virus to keep the virus within a managable range.
Hence the 5 government tests to end lockdown.
Its not 'time to suck it up' just yet, because we aren't quite at a point which is managable. But it will be in the coming weeks.
The authorities haven't been sitting on their arses in competitive lockdown sunbathing. If other people have been to aid the work of this crisis management mitigation planning and preparation, thats fine by me. Its not an excercise in jealously about why life isn't fair.
I don't like the idea of lockdown being ended soon, but I do understand the need to balance risks and the need to mitigate and that it has to. There isn't a choice. But the timing has to be the best possible - and that has to be when we are ready and not before - otherwise we will have wasted the efforts of the last 6 weeks and we will be in a worse position.
This understanding is unlike the OP who thinks they know better than experts and we should do it NOW, just BECAUSE without grasping in any shape or form why its being done. But then we've had enough of experts haven't we?
People like the OP might want to reflect on makes us a civilised society that tries to lock after as many people as possible rather than taking the attitude that we should sacrifice those who are weakest when the going gets tough. Because if you want to go down that route, it soon gets to the point that poorer people who can't afford health care should be left to day for the benefit of the rest of the population...
