You can not be completely dependent on bitcoin right because bitcoin will provide a means of transaction in future, and in that Government will put its charge also but only real money will run in the market. The Government does not want that their finances are completely out of their hands
If bitcoin is one of the options that you employ for yourself, then you are far from making yourself "completely dependent on bitcoin."
Each person needs to figure out and then choose their level of allocation into bitcoin and with having some bitcoin in your holdings, you likely give yourself more rather than fewer options.
Regarding what the government wants or what they may want or what they think they want, that is both an evolving thing but it is also not any kind of specific thing because we have all kinds of governments and their ways of coordinating what they supposedly want is also not necessarily clear.
Bitcoin seems to achieve a lot of things that governments say that they want, but frequently those governments with money printing capacities might not want bitcoin and/or they might be threatened by bitcoin because bitcoin reduces their frequently abused capacities when it comes to money printing and various ways that they control the money supply - which ultimately seems to get back to various ways (especially in recent times) that governments have been debasing the value of money through printing techniques but then mostly lying (unless they are confused as well) in regards to either what they are doing or the negative effects that monetary debasement seems to have.
I would disagree with saying bitcoin is the only escape route but would agree it's one of, if not the best, escape route from financial oppression and tyranny due to over inflation caused by "printing" unlimited money.
Yes, technically you are correct that bitcoin is not the "only" escape route, and it likely would not be very smart for people to fail/refuse to diversify the various ways that they hold their wealth and then also if they fail/refuse to account for their own individual circumstances including but not limited to cashflow, other investments, view of bitcoin as compared with other investments, timeline, risk tolerance, time, skills and abilities to strategize, plan, research and learn along the way including tweaking strategies from time to time to consider trading, reallocating, use of leverage and/or financial instruments.
Bitcoin has a lot of advantages over a lot of assets/currencies, yet getting too much exposure to a good thing has its own likely problems.
