I like privacy too, but currently way too much harm is being made by the fact that people can keep their income private. Think about all the corruption using offshore accounts. It's not even cryptocurrency, just some other solutions. In a world where everyone's income is public, politicians won't be able to explain their financial gains. And you wouldn't have to worry about whether you're underpaid at work compared to your colleagues who do the same job with the same efficiency. And if you receive your income from a legitimate source, you earn that money, then it's nothing to be ashamed of. And nobody gives a damn crap if you use it to buy your toilet paper. On the other hand, if you're buying a HIMARS system on the black market, and then pass it onto the terrorists, you would very well deserve to be caught by the authorities and then rot in jail for decades.
Of course, this is a very extreme scenario. I'm not saying the ideal world is when everyone's finances are flat out published and advertised like "hey, look, I'm rich and ready to get robbed", but this is definitely an area where total privacy hasn't worked out well.
I used it every day, when I had it. I would still use it every day if I had it. Sadly I don't have it anymore.
