You're doing a huge logical jump in your first point. Alcohol and cigarettes are physical goods, digital ID is not, but you're proposing a system that turns it into a physical problem. I'm merely pointing out that's what you're doing and the issues with it.

Second, it doesn't matter what it costs, it's inconvenient and I already spent time (possibly money too) obtaining a government ID... on top of a theoretical mandate that says I need to show the ID on a bunch of websites.

Third, I'm not sure I follow your point on alcohol restrictions creating winners? The non-profit idea could potentially be good, but I'm not hopeful that real world legislation would be crafted that way.

EDIT: also more on #1 and "severe consequences" for re-selling... yes that's exactly what we want to avoid: creating more reasons to put people in prison and a bigger burden on law enforcement and the court system.
