It’s not much harder to do with real money. India, a country of 1.3 billion people, did it in 2016 with “demonetisation” of specific high value currency denominations. [1] Some people died because they couldn’t get their own money from the banks. One could say that these people didn’t get their money. Millions lost jobs and their livelihood because they couldn’t get their money.

Other countries have done somewhat similar things over the last century.

On the same topic, real currency can become or be made worthless due to hyperinflation (and even normal inflation).
