It means your government wants to you keep working regardless of your saving but you're going to use bitcoin to save you from that situation? Why not we assume that bitcoin was created for both the purposes of getting us rich as well as make us free? Because, the reason why bitcoin was created definitely perspective; it will look like how you are approaching it and based what are your needs.
In my opinion bitcoin was created to get rid of all the hassles of our traditional banking like giving the power of banking back to the common people themselves. But to make it popular, it was designed in a way which will be helping us to be richer but that is only in short-term property of bitcoin or we can assume them it like a temporary characteristic.
I can't stress this enough ; BOTH CAN HAPPEN. Why do people who know that bitcoin is an asset that could be traded and make more fiat profit for you AND it could also be something that will set you free if you keep holding it for a long time. You can mine it, trade it, invest in it, use it, earn it, spend it, throw it away do whatever you want with it, it is a personal preference and it wasn't created to do anything, it was created as a test and as long as that happens to stay and work that means it worked. You think bitcoin is the first "e-money" that was ever created?
There has been many for the past 30 years, and this one was just another that happen to end up working. This is why there is no specific reason and a method how you should use it, it is just something that was done and now we took it over, and we can do whatever we want with it.
