Does bitcoin really do any of those things? Right now, btc core is not an alternative to cash- a problem that maybe will be fixed in time, but currently only seems to be getting worse. If bitcoin really did take off as a global currency, the IRS would audit unreported bitcoin transactions- and it'd have your financial records because the corporations and individuals you interact act with would cooperate, and it'd only need a few to start to deanonymize you. It seems like the blockchain would almost make the tax job easier, because all transactions are public unless people move from bitcoin to a zerocoin model. Even then, the IRS would pursue those who didn't report and have transaction information from vendors to work to identify fraud.
So, bitcoin doesn't seem like an alternative to taxes. Also have no idea what it has to do with most government regulation. And, is it really an alternative to the financial system? Yes, people can use bitcoin instead of a checkings or savings account- but still need to use traditional services to invest in the market, and the financial system will continue humming along making more money from money and making gobs of money profiting off everyone else's market inefficiency whether it's working in usd or btc.
So, what are we left with? It seems like core btc is only an alternative to a speculative investment in something that the federal reserve cannot print. And believe it or not, the vast majority of this country either doesn't care about quantitative easing, or believes in basic macroeconomics. Core right now seems to just be a LARP fantasy for libertarians convinced that "this time we can finally get rid of the evil Fed and their evil money printing". It'll never happen, and if it does offfer any kind of freedom, it's the freedom to go back to pre-fiat boom and bust cycles of economic hell detached from modern macroeconomic theory.
