What advantage does this have over a thick, pretty foil envelope with nice embossing telling people what the printed code/long barcode/micro-SD card inside is for?
The psychology of cash and how people hold and spend it is unique from any other physical financial instruments. They keep it safer and spend less than they would with credit cards or debit cards.
A completely foreign object with a printed key might be kept safe -- but it isn't intuitive to do so. We heard multiple stories of people gifting Bitcoin at events like weddings only for private keys to be tossed out with cards.
How can people hold on onto their birth certificate? The infrastructure is already in place for that, so the problem is that they didn’t understand that that piece of paper was worth money.
Handing over a monopoly bill will have the same fate. You can’t keep it in your wallet and it can be lost easily.
Either way this is a ridiculous project and would probably best be served by the concept of “gift card” instead, given your explanation.
Sorry, I don't follow any of your reasoning here. Monopoly money is a low cost print with little detail on standard paper. People don't throw away foreign currency simply because they don't know what it's worth. I'd recommend taking a look at the psychology of cash to understand my point better.
Are you sure? If I find a single bill from a random country I assume the worth isn't a whole lot. Such bills get stashed in the souvenir box which may or may not be thrown out at any point when space runs out.

I don't think the birth certificate analogy is that hard to follow. It's easier to hold onto a US-letter-sized document than it is to save a single bill that you should not place in a wallet.
