Yeah, government currency does have those problems. I'm not sure I'd even classify it as real money to begin with, it's just a scheme governments impose on their populations. Real money is precious metals: naturally scarce, malleable, fungible, divisible, universally recognized as valuable. A very small set of cryptocurrencies also have a shot at becoming real money one day.
I don't think this can be called artificial scarcity though. It's real scarcity that's gradually inflated away by governments and banks. Data is already infinitely abundant as soon as it's created.
Have you somehow modelled how the global economy would change if copyright was 10 years and fiat currency didn't exist and people used gold instead? Without that, you're living in fantasy land. You can make any idea seem better if you just make up the consequences in a way that favors your idea.
