A "ban" could be put in place, but it's unlikely to be an effective ban.  Unless you're getting your coins mixed up again, maybe?  Usage of BSV would be comparatively easier to restrict by a government than usage of BTC.  BSV has fewer nodes, limited infrastructure, weak decentralisation, etc.  Not to mention the so-called leadership's stance on regulatory compliance.  You'll put your hands up and surrender when you're told to.
