Sorry but that's bullshit. There's no such thing as zero risk, only measures of vanishingly small risk.
So yes, There's always ways to eliminate the risk (specifically from covid) even further, scrap all exemptions, ban all flights, lockdown all of society.
So what does this mean?.... yup they are morons and oppressive dictators only, nothing more, no justification at all in the amount of risk they claim they're attempting to eliminate, it's all simply lies.
