Good lord what are we living in the days of the NAZIS. THis is america people, not hard to find info on anyone, no ones using what you buy on newegg and amazon against you lol, Reading too many books and watching too many movies or something lol. Ok, I understand it can happen, but christ we have grown as a country, if you live in the USA, theres a pretty damn good chance, like 99 percent, that its not going to effect your freedom or what happens to you in your lifetime. We only live for about 60 to 70 years, something major would have to change for that to matter and at that point, bitcoin wouldnt matter or even be discussed, we would be facing much more important problems then buying something online lol.
Likely some Germans said the very same thing circa 1930. Is there something that makes Americans genetically superior to other nationalities? That what has happened in other countries in the past 3 centuries is impossible in the United States. If you think so then you are naive.
Your shortsightedness of thinking only for your generation is small. What about your children's generation or their children. Privacy is a human right. It doesn't matter if the govt will use what I buy at newegg against me or not. They simply have no right to that information. Tools like Bitcoin put the power back with the people.
Lastly as others have pointed out Bitcoin isn't just for America. Try to limit the Amerocentrism just a little bit. Bitcoin may be the most useful in emerging nations (which tend to have volatile currencies, and periods of rampant inflation) and totalitarian regimes (where privacy has a higher value and utility).
