Personal opinion, Delta 8 works exactly like regular weed (D9), but without feeling spacey. Heart rate rise, body high and hunger like crazy. Pain relief is very present. CBD, I've felt next to nothing - ever. Placebo at best. That's been very consistent in my group of friends and family.
I would image that if I sold CBD, I'd be wanting D8 to be regulated. As a consumer, it would as always be an inefficient and burdensome governmental hinderance.
That said, there are already a number of states that don't allow it to be shipped in...
