For someone in a another country, the current 8%+ inflation of US Dollar is far from negligible, especially when the dilution drivers such as stimulus packages are mostly only to the benefit of US Citizens. Physical bearer assets like cash or gold seem to be far worse than any digital solution in that they can be seized with physical force and are not possible to conceal. Bitcoin's advantage is further that it is digital and permissionless. So just like the US Government can't prevent drug cartels from using cash, it or any other government can't prevent anyone from using bitcoin.
