The human rights angle has been argued IIRC and the conclusion of it was the measures represented a departure from them but that the right to life trumped them.
That same still exist when very few people even get sick and die? It might got changed a little bit and if you have lockdown people already for two months, assume that you would need quite strong reason to continue it for ever.
At least government there seem to think people already could start to have some rights again instead of forced to stay home but don't really see where's that other argument to force whole population to do it, like said, nobody force anyone to get in places where they don't like to go.
With these numbers it's just hard to see it be reasonable anymore to continue it much further.
