These laws are definitely binding on the state and local level, where most drug policing is done. Think low-level possession of small amounts. Which, having been decriminalized, means a marijuana user doesn't have to fear the officers that they are far more likely to interact with.

Still, there is absolutely a need for reform on a federal level, even if it's just a law that provides an exception for states with a legalization regime. Otherwise I think you're mostly right. Prosecutorial discretion is the only thing that prevents the feds from swooping in at any given moment.
