This. If you can't spot obvious logical fallacies, and repeat them uncritically, then why should I trust you? Cryptocurrency evangelists tend to set up straw man arguments then claim to present solutions that don't even solve those problems!
Personally, I want a trusted third party to mediate disputes. If transactions are completely non- reversible, and there is no, dispute, mediation, or remediation possible, the need for trust does NOT go away, it just shifts so that you must trust every entity you transact with.
