Just because there’s technically no mechanism within the protocol to reverse the transaction does not suddenly make it legal to keep the money right? You could spend all the money accidentally wired to you and have nothing left to your name, but you still owe that money. So you could keep the ill-gotten crypto but still be liable for civil or criminal charges.
You'd be making the argument that the contract was followed perfectly, and it decided that you should have the money. If the code is the contract, the bugs are what everyone signed up for.
