I agree its mother natures/God's will for whatever happens, we can't control it or accurately predict what the future may-hold.
For me these maybe the possible positive outcomes, others may not see it this way are:
Sikhs will learn to rely on each other and help each other. And be less tolerant of arrogant self promoting Sikhs who giving away sangat's hard earned money donations, food and aid to non-believers outside of guru's home and guru's kitchen. The sangat will come down on them like a tonne of bricks to stop their madness soon enough or just not donate to them.
More people will turn to God and learn about and convert to sikhi. Liberal no IQ Sikhs will start to come back to the faith. Others with some intelligence will use their time to learn about Sikh faith and history read up on important aspects of Sikhi they may have misjudged or not understood before.
Hardship will make Sikhs more eager to defend Sikhi and less tolerant of aggressors like in 1980s/90s
House prices will come down eventually meaning they will start to become affordable for first time buyers
During the lock down or periods of unemployment we can use our time more time to better educate ourselves
There's less pollution in the skies and rivers now that less people are out and about in heavy industries.
The rich and poor are in the same boat this virus has shown it doesn't discriminate nations, ethnicity, religions, wealth, etc. It has leveled everyone to the same level of having to stay indoors unless they an essential worker

Disgusting muslim zealots like the ones below:
