Kids can still order wine and cigars from the internet without ID. When I was a child I did it. The law doesn't require signature on delivery, and the deliveryman has no idea what's inside and thus will accept signature from anyone including me when I was a child.

The regulations on selling tobacco in person AFAIK are only for cigarette and cigeratte labeled type rolling tobacco. You can still order perfectly cigarette smokable "pipe" tobacco online straight from an internet "vending machine" and probably a real one. Very few people know this though because it turns out to not actually be a much of a problem.

Or, heaven forbid, a kid could spill a pinch of bread yeast into a bottle of fruit juice, wait a week or so, put it in the freezer overnight, and get some alcohol stronger than wine! No internet required!

In practice I think most young people who want to drink will just get it from a "cool older brother" or steal it, whether from parents or corner stores. At least that is what I saw in semi-rural America.

People will do what they want to do, with or without vending machines and online ordering.
