They’ll probably settle on creating a higher denomination. I mean, it’s not like it would be hard to justify having a higher denomination. The US Treasury used to issue higher denomination bank notes., but the highest has been the $100 note since 1934. We’ve had quite a lot of cumulative inflation since then. Sure, cash is less important now than it was in the past. But if just by inflation, a $1000 note would be appropriate. So maybe as a compromise you issue $250 and $500 notes.
Or maybe he’ll just mint a ten trillion dollar platinum coin with his mug on it. Then have the treasury deposit it in the president’s personal bank account as “a tip for good public service.”
When the cost to try something is virtually zero, you don’t have to try very hard. If only one in ten thousand people will fall for a scam, then millions of attempts will still get you thousands of successes.
