Earlier quoted context omitted.
It wasn't obvious to me either. It sounded like you made an argument that at least 30% of people shouldn't be allowed to drive, and then leaping to that leading to some sort of societal bifurcation? Your argument or point isn't obvious or clear at all.
>It sounded like you made an argument that at least 30% of people shouldn't be allowed to drive, and then leaping to that leading to some sort of societal bifurcation? Aha, a tangible argument. You don't see the possibility of social bifurcation from 30% of the population not being allowed to drive? Most tradie jobs require a car. It's very hard to be an electrician, plumber, chippie etc. that services homes as if yo…
Then how do people do those jobs in countries that do meaningfully select for good drivers, instead of dispensing licenses to all comers? Last I checked, continental Europe hasn't entirely descended into disrepair, because not everyone can drive.
If your position is that overnight switching to a tough drivers licensure regime would be disruptive, I can only say, "Of course it would". Literally no-one is advocating that, either in this thread, or in The Fine Article, however, so I'm vague on its relevance.
> My point was that the argument "we shouldn't let people do this because it has costs to society" doesn't really go anywhere as an argument.
Which would be an interesting discussion if that was the argument being made. Sin taxes aren't "We shouldn't let people do this", and it's a fundamental mischaracterization of them to say they are. They discourage it, sure. They can also be used to mitigate the cost of the "sin" in question.
But it is fundamentally incompatible with most of the goals of a sin tax, to be used to outright prevent the thing being taxed.
