> 1. We trust the coders to know what is best for us. > 2. You can write perfect code so that our money is safe. > 3. The price will never plummet.
Nobody is asking that. The source code is public, read it and decide for yourself. Good luck doing that at your local bank. There are plenty of stablecoins, you don't have to take on crypto exposure.
> 1. Mt. Gox Failure
Totally irrelevant.
> 2. DAO Failure
Sure, a public commons infrastructure will elicit a lot of bad projects. Just like the vast majority of open source projects are bad. This is not an indictment of open source.
> 3. First BTC price crash
Irrelevant.
> 4. USDT regulatory concerns
Use one of the many other stablecoins, then. This is the beauty of the system. It's actually open, so there are a diversity of issuers. You could even start one yourself, if you wanted.
> 5. Lack of learning from failures
There is an enormous amount of learning from failures. If you believe there isn't, you aren't paying attention.
> 6. Politics still exist, they just moved to the coding layer
Yes, this is true. However, this layer is thin, by design. That means the layers above it, which implement most of the relevant functionality, are a diverse ecosystem of choice. Contrast to the thickness of politics in other domains.
> 7. Willful ignorance of the scams and crimes cryptocurrencies has enabled > 7.1 Because somehow cryptocurrency is better for us.
New technology brings about scams roughly in proportion to its power. The internet enabled tons of scams. Fiat currency enabled tons of scams. Coinage enabled tons of scams. And so did banks, particularly of the fractional reserve variety.
That doesn't mean scams are good or should be tolerated. But it takes time to develop the social and political conventions to deal with them. I believe that process is taking place in crypto, though perhaps not as quickly as we'd like. I think if you look back at the history of other comparable technologies, you will see that crypto is pretty far ahead of the game in this regard, though.
> 8. Hype over price security and software security > 8.1 Because somehow cryptocurrency is better for us.
Sure. Lots of elements of crypto are overhyped. Overhype comes along with any transformative technology. See hype about carbon nanotubes, nuclear power, 3d printing, etc. Hype is an indictment of people, not technology.
