Most people, especially within this forum care about privacy because they want to hide their income from the authorities. They dislike taxes and they don't wanna mess with all the laws that surround cryptocurrencies. I dislike most taxes as well, but tax evasion is illegal and I don't encourage it.
Maybe I'm naive, but I always assumed the majority of Bitcoin users doesn't do it to evade taxes. There's one very simple reason: if your small Bitcoin investment turns into a small fortune, you
want to be able to tell a honest story so you can legally use your money to buy things.

My governments' greed keeps growing. A few years ago, the "wealth tax" was 1.2% per year. Now it's 2.12%, next year they're planning to increase it to 2.84%. I'm pretty sure that's by far the highest wealth tax on the planet.
