In natural units, it is 1 (or at least ℏ is set to 1).* That just restates the mystery using different words because natural units are based on physical constants. That restatement simplifies things in some circumstances but it has disadvantages, if you just use natural units in your equations you're throwing away information. For the equation X/Y=1 X and Y can have a infinite number of values and the equation is still mathematically true, but if X and Y are physical universal constants then you might want to know the specific 2 values out of that infinity that also make it physically true. If all I know is 1 there is no way I can get back X and Y, but if I know X and Y I can always get 1.
