Its also undeniable that enforcing these things has real social cost and harms. In this balance I am of the opinion that it would be far superior to have a different policy.
> You're presupposing a direction of causation here. Your average street gang does not exist because of drug dealing or consumption (and indeed, violent street gangs long predate any restrictions on drugs or alcohol). They deal in drugs because it's easy money, but arise for other reasons.
That does not mean that these gangs would be much weaker and therefore less important if they could not make easy money. These are mutually supportive, a tight group can do well in a illegal market, and because of that it can produce benefits for its members, increasing memberships and power.
