“The poorest households in the US spend 9% of their income on lottery tickets, showing that you can't legislate people out of misusing their funds.”
You’ve explained why it’s urgent that we outlaw lottery tickets. For most of USA history Protestant and Catholic leaders were unified in their opposition to all forms of gambling, and so lottery tickets were unthinkable for most of USA history. And every progressive activist that I know personally would like to see an end to lottery tickets and other forms of de facto regressive taxation. Lottery tickets, like other forms of gambling, tend to undermine habits of thrift and sobriety.
I agree with your implied analogy — ICOs are like lottery tickets. That’s why they should be banned.
