Because, you know, policy that harms more than it heals, laws that create criminals instead of mitigating criminality, is a little bit stupid.
It took 13 years for the United States to come to its senses and end Prohibition, 13 years in which people kept drinking, otherwise law-abiding citizens became criminals and crime syndicates arose and flourished. It has been more than 40 years since Congress passed the current ban on marijuana, inflicting great harm on society just to prohibit a substance far less dangerous than alcohol.
The federal government should repeal the ban on marijuana.
It seems silly to call them brave – but, I think, that among other compliments are deserved.
