Why can it not be sold to those of us in the restricted states mentioned above?

Pretty sure because they haven't applied for it to be registered. If it is the exact formula as Tenacity, then Tenacity is only restricted in AK and PR. There is another generic 40% mesotrione product restricted in less states than this Meso 4SC, AK, AZ, CA, HI, and this one is ok for CA. https://www.amazon.com/ITS-Supply-Torocity-Mesotrione-Herbicide/dp/B08D8MBSK1
