I think what he/she is saying is that the individual governments involved, and the WHO, have screwed up this pandemic response so bad one wonders if these large organizations in general can be trusted to provide any competent standards on anything.
Incidentally, you make an assumption that cars would not be safe if it were not for government standards. The reality is that manufactures would have huge incentives to make their products safe due to safety being a key thing the consumer looks for in purchase a car - and also to avoid lawsuits. Trade organizations and safety rating company (UL) would also be employed. Consumers could choose their own level of safety vs. cost when shopping for a car.
But largely - these things come down to freedom. Some want to take these freedoms away from people and have the choice made for them by the government. The State will tell you how large a soft drink you can have - it is not up to you to think you know what is best for yourself...
