I don't understand all the kerfuffle. I'm from EU and was looking into investing earlier into Nasdaq symbols, iow before my bank decides to bother letting me pick some crumbs from their plate. So I look around and I figure that what you can do on these online trading platform is to buy some glass-beads from them that happen to correspond to IRL stocks. IOW, these folks are data-mining user sentiment to place orders while offloading risk. Isn't it the same with RH? Aren't they just saying "you can play along, just not with these beads. Too risky for us." Or is RH a straightforward stock broker?
