> holding parents accountable for what their children consume

There is a local dive bar down the street. I haven't expressly told my kids that entering and ordering an alcoholic drink is forbidden. In fact, that place has a hamburger stand out front on weekends and I wouldn't discourage my kids from trying it out if they were out exploring. I still expect that the bartender would check their ID before pulling a pint for them.

It takes a village to raise a child. There are no panopticons for sale the next isle over from car seats. We are doing our best with very limited tooling from the client to across the network (of which the tremendously incompetent schools make a mockery with an endless parade of new services and cross dependencies). It will take a whole of society effort to lower risks.
