There are some other stablecoins, like USDC (about half the size of Tether. Why would Tether need to be closed down while USC not? Or do you think all of them should be shut down? Tether is just an IOU note. I don't have problems with IOU notes, unless someone forces me to use them. Personally I haven't used tether and probably never will, however I don't have any problem if someone else wants to use it.
