You can't think of risk in terms of binaries; bad things are still possible with the best safety technologies, but that doesn't mean those technologies aren't worthwhile.

Edit: taking your analogy less literally, it seems the issue here is the socially acceptable level of risk. The health risks of covid are demonstrable and apparent.
