Yes. We need as many regulations as we can get... so that eventually cryptocurrencies become illegal, thus create a new, parallel economy... and eventually overthrow the original one.
Do I understand you correctly? You want them to BAN crpytocurrencies and only then the parallel econony will emerge? This scenario is crazy and very unlikely. If they ban crypto, 99% of people will jump off the train and people who will remain will not be able to create parallel economy. Cryptocurrencies and blockchain technology needs to work in hand with the classical economy.
Not if we get enough people to rebel against the oppressive reins of world governments. Viva la revolución!
