Well, for the energy consumption part yes. There the need for banning crypto concerns those "currencies" which do use PoW. Like Bitcoin what the article was about. Banning crypto in a practical sense is actually quite easy. Prohibit any business and any bank in dealing with them. If you cannot do legal transactions with e.g. Bitcoins any more, the market mostly dries up. It is not necessary to ban any single coin in existance, but its wide-scale usage in the normal economy. By the way, there was never an attempt to ban torrents itself. That would have been reasonably easy on a protocol level. It was about banning illegal torrents. As in the content, not the protocol.
