Neither bitcoin nor paper money has any real value, but notes have national credit support, and what if bitcoin also gets national credit? The government will lose its macro-control policy but it can also effectively eliminate inflation, two relative ratios. Is that a good result? Of course, I know that the government is very unlikely to support bitcoin, but who knows?
This can happen if we all turn away from paper money and banks. But you can see the paper money still decides bitcoin and people are still dominated by the bank, it is difficult for government to support bitcoin
