The smartphone wasn't a new invention - but a continuation of the mobile phone. Mobile phones had already hit mass adoption in the developed world before the smartphone appeared. People knew what they wanted because they were already using the technology. This isn't the case with bitcoin, which most people have never used. The more accurate comparison is mobile phones in the 1980s, which people didn't know that they needed or wanted. In fact, many laughed at the idea of carrying around a briefcase to call people on the move, which was necessary as the early handsets weighed in at several kilograms. Very few had the insight at that time to envision the phones of today. The relevance of Bitcoin has already been explained to you: it provides for the first time in history, a form of money which is inflation-proof, censorship-resistant, easily verifiable and possibly private (or at least plausibly deniable), making it potentially unconfiscatable. Bitcoin isn't merely about transaction costs or means of paying people. It is about having sound money. It has a use case for anybody who wants to save money, which is impossible to do with fiat money, because it is rapidly devalued due to the monetary policy of central banks. Other "crypto" or "blockchain" is irrelevant. We can agree on that. Only Bitcoin matters. Just because you have not seen the need for Bitcoin yet, does not mean there is no need for it. You are like those who would mock the mobile phone or the dial up internet of the '80s, with very little insight into what value Bitcoin can bring to the world. Bitcoin will be used to bypass warrantless surveillance and State-enforced restrictions, and yes, even to avoid paying taxes - which you might consider "criminal behavior," but this merely highlights your state-worshipping world view. Tax is theft - and a significant amount of "criminal behaviour" is coming directly from the State itself.
