It has been around a lot more than a "couple" of years.  And fiat money continually implodes over time, so one would say that "normal" money doesn't survive decades.  For example the dollar (and most fiat does worse) has lost half its purchasing power aka value in 30 years.  Same with the Euro.  And around ~98-99% since the Fed was created.  Many fiat currencies have done much worse and blown up by 100s or 1000s or much more percentages of inflation over time.  Look at Germany multiple times between 90-120 years ago, the USSR, China Argentina, Zimbabwe, Venezuela etc.   Anywhere you have a fiat based monetary system the temptation is to impose a non-free economic system - socialism, communism etc - which inevitably leads to economic destruction and the loss of economic and other freedoms.  A non-fiat based system provides some protection against it.

Now if you mean "normal money" like gold or silver that lasted thousands of years without the need to have someone pretend to "guarantee" the value, that is a different question.
