Neither of these are true. 'These people' don't want to let any particular party regulate their use of money, for better or worse. By using bitcoin, you implicitly accept the risks of a decentralized currency. Until there exists some good way of decentralized regulation, if its even possible[1], these sort of risks become a simple fact of life, a cost of doing business.
Bitcoin users and proponents dont "think they don't need regulation", they reject it. They don't "think they won't fall for scams", they accept the risk and possibility. They don't think "regulations are for the weak", they think regulations are for people who accept their government knowing everything about their finances and need transactional legal accountability. Your comment, and the parent one, are nothing more than really weak strawmen.
