> This isn't some incidental detail - it's the entire reason why the banking and credit card industry doesn't want to interact with cannabis right now.

FYI - Banks do work with cannabis in states where it's legal. Those banks just can't be national banks - they have to be state ones that are regulated by the state. In other words, Chase/BoA/etc. can't touch it because they operate at the federal level and are highly regulated.
