Curious: are you ok with the other laws that are in place in the world to prevent underage people to engage with all sorts of activities? Like, for example, having to show an ID to being able to purchase alcohol?
The difference is the internet is forever. A one-time unrecorded transaction like showing your ID at the bar is not. It is a false equivalence.
Not only is the internet forever, but what is on it grows like a cancer and gets aggregated, sold, bundled, cross-linked with red yarn, multiplied, and multiplexed. Why would you ever want cancer?
I'm a lot more okay with that because alcohol purchasing doesn't have free speech implications.
It's weird how radicalized people get about banning books compared to banning the internet.
They aren't comparable. Showing an ID to a staff member isn't stripping my anonymity. I know the retailer won't have that on file forever, tied to me on subsequent visits. Also they stop ID'ing you after a certain age ;)
There isn't any way to achieve the same digitally.
