Your suggestion has at least two severe issues:

• It doesn’t scale. The people that can and want to “wait until they’re ready” probably are doing that already. Meanwhile, the large, unwashed majority does whatever they feel like, and why would they want that to change?
• It takes away personal liberty and punishes people who “cannot control themselves,” giving way to social authoritarianism. To me, that’s the exact opposite of what any elected government should do: to make people’s lives better.

I remember ice-skating every winter as a kid. Rivers were frozen over solid, too. Sometimes, there were two separate layers of ice on top of each other, each being several cm thick. It kind of went away in the late 90s. I guess everybody just thought the ice and snow would return someday. Now even snow has gotten really, really rare where I live.

At least in my current job. There are nice AND useful ones out there, but in my dept., there’s positively neither.
