This is an easy and obvious exploit so an attacker would need to extract the data from all sources ASAP. High risk of getting caught and ending in jail to be honest for measly 2BTC. Not worth it for anyone in the US or even Europe.

Lots of crimes are not "worth it". And yet criminals do it anyway. Because criminals (nor most humans) are not perfectly rational.
There's routinely reports where people try to rob a gas station with a loaded gun - a $200 haul if everything goes perfect. It doesn't and now they have 10 years in jail...
Yeah Sam Bankman Fried probably had the skills and connections and trust to coast through life. But instead he chose to commit the most egregious of financial fraud.
I would strongly argue that almost all crime is irrationally - take it to the game theory strategies of tit-for-tat and such.
