Not everyone agrees on what is "silly" (or to call it what we mean - dangerous). Hence the need for a baseline level of safety expectations that apply to everyone, remembering that some people will have legitimate medical, mental or developmental conditions which mean they cannot judge as well as other people what is sensible or dangerous. Other people are just idiots, but that doesn't mean they deserve to be hurt or injured because of it.
Or, in other words, I can't choose what I believe to be sensible or not, no matter how well-based in evidence, instead I have to yield to the tyranny of the experts and/or the tyranny of the majority. But 'its for my own good' so apparently that's a good thing.
Given we have the NHS, if someone injures themselves because they are being stupid (or again, doing something that is dangerous), the rest of us pick up the cost so it is in societies interest to try to reduce the number of these cases.
I see people going off for skiing holidays every year. Quite often when you next see them they're in a plaster cast. Should the state and/or their employer ban them from going skiing? The logic would appear to be the same.
If you have a system where someone could opt out of wearing PPE or of H&S at work legislation, you would very quickly see employers trying to force staff to work in unsafe manners to save money. That absolutely is not a road we should be going down.
I agree that this is a concern, and needs to be carefully managed.
It is actually quite rare that someone's choice to do something dangerous doesn't put someone else in danger too. Even if you think you are just affected yourself - in relaity you likely affect everyone else around you - from new people at work who may be trying to understand what is expected of them, to the people who end up helping you when you do hurt yourself etc etc. It very rarely is limited to just you and you alone.
But that applies to every single action every one of us does. Everything we do - or don't do - has some element of risk to ourselves and to others. The question is how great do these risks have to be to justify using the full power of the state to prevent us from taking such risks? I think the bar needs to be pretty high for that.
We have to find a balance between living a life that is full and enjoyable, while also not being recklessly irresponsible to the life and enjoyment of others. Simply saying that the state should prevent me from doing thing X because it may cause some possible random consequence for person Y, or person Z twenty years frm now, isn't good enough.
but this idea that governments have no business deciding what is safe or not is clearly and obviously rubbish.
I don't think anyone is suggesting that the government has no role. I'm happy for them to issue well-founded advice. But here we're talking about the government putting all sorts of laws in place to *enforce* its advice, which is more problematic.
This is a perfect example. You are ignoring the fact that someone not wearing a seatbelt can cause injuries to other people in the car.
E.g. a passenger in the backseat of a car not wearing a seatbelt can be thrown forwards in a crash, hitting the seat in front with enough force to actually do harm to the person sitting in that front seat, even if that person in the front is wearing a seatbelt.
So you are willing to risk injury to another person because you want people to be allowed to ignore a safety measure. That starts to ring somewhat familiar and a bit more on topic to this thread than the rest of my post!
I haven't ignored it, but the risk to others is rather smaller than the risk to myself, so I didn't emphasise it either. In this case, yes, I do believe the risks to others are sufficiently small that mitigating it, or not, should be a matter for my conscience, not the state and the law. Nevertheless, as I stated above, I would wear a (two-strap) seatbelt in a car whether or not the law required it, because I think the data on it is clear that it is a good idea.
Some people appear to want to live in a society where the only actions that are permitted (by force of law, the police, fines and prison!) are those that are assessed and evaluated to be sufficiently 'safe' both for the individual and for the entire population by a group of politicans, scientists and/or media - whether that assessment is reasonable (eg. seatbelts) or nonsense (eg. masks).
Well, some of us very much don't want to live in that sort of society, and if that means taking small risks with my health and well-being, and accepting that there is some degree of risk from my actions to others - and that as long as I'm not being very reckless than that is acceptable, that to me is perfectly fine, and more than that, I'd say it is the only 'human' way to live.
