So two things :

1)people are well aware that transactions in the traditional finance world aren’t final some people love/hate it unconditionally while others’ feelings about it change depending on the situation

2)Regarding the bitcoin theft law enforcement agents got in control of the thief’s private keys they didn’t reverse the transaction if someone sent money to my bank account and someone got my account details and was able to withdraw the funds no sensible person would say that the bank reversed the transaction so why it would be any different here
