I love arguments like this. How did the federal government end up nationally banning all fun drugs aside from nicotine and alcohol? (it just did it, and even when states legalise e.g. weed, weed vendors are locked out of the proper banking system: https://en.wikipedia.org/wiki/Comprehensive_Drug_Abuse_Prevention_and_Control_Act_of_1970 https://en.wikipedia.org/wiki/Comprehensive_Drug_Abuse_Preve...). How did the federal government make ~every state have the same (mad) drinking age of 21? (federal highway funding blackmail: https://en.wikipedia.org/wiki/National_Minimum_Drinking_Age_Act https://en.wikipedia.org/wiki/National_Minimum_Drinking_Age_...). the constitution is not an actual barrier to the federal government doing things over the heads of states.
