No it's not designed to LOSE value, it doesn't just go away. It is designed make YOU to lose value and MOVE that value to those who control it. It has been that way for at least a hundred years. 

Would it be 'offensive' if I had slaves? How about if I only made them work for 10% of the year? I'm only extracting 10% of their value from them, and doing nothing to gain it except 'possessing' them... 

But stealing their value and life energy is INHERENTLY EVIL, and thus offensive.

Fiat makes slaves of everyone, and has done so for a century. There is FINALLY something that they can NOT control, which on a long enough time frame easily overcomes that, but it is still just and right to take offense at, and decry their evil system.
