When governments make exact copy of existing fiat money (i.e. engage in money printing) they increase supply of fiat money and as a result cause inflation, which decrease the value of fiat money existing before the money printer was turned on. So while such a copy did not completely eliminate your ability to use your money, it did in fact decreased its utility. And indeed can be a valid case of "stealing".
It's not stealing, government didn't steal anyone's money, they just devalued it. In a similar sense, gold miners are increasing the supply of gold and lowering its price, but they still aren't stealing anyone's gold - they're making more. The fact that fiat money is completely fictional does make it more prone to systemic abuse - but even in that case, what the government is taking away from people is value and labor, not money itself, and those two are a little more abstract and harder to reason about.
The word "stealing" has a specific meaning related to physically taking something away from someone else, let's not use it in contexts where it doesn't apply. Especially when the use of the word is mostly perpetuated by copyright holders who want to persuade the public that not giving money to them is equal to stealing from them. That's bullshit, and it will always be bullshit. To me, it sounds horribly similar to narcissistic abuse: "How could you not give money to me? Do you have any idea how much that hurts me?".
> When all my fiat money is taken, I cannot use it anymore, therefore it's removed.
Ok, so if your intellectual property is stolen ... err, sorry, "copied" of course, how do you get monetized for those "copied" copies? By your initial statement it's not removed, now you tell me it is? Weird.
There's no such thing as "intellectual property". If you don't want other people learning the information your mind has come up with, don't release it into the public where it can be easily shared.
> but I want money! I don't care if everyone else loses their right to sharing information!
