You don't own crypto, either - the consensus does. If the consensus is that you don't have the crypto (such as if they fork after you successfully stole millions of dollars worth of crypto on the main chain), you don't.
Sorry, I didn't mean to suggest that you did own crypto. I was singling it out largely because the normal dispute resolution process, the courts and legal system, are irrelevant to crypto. You can't sue bitcoin to make the blockchain reverse a fraudulent transaction the same way you can (ostensibly) sue a bank.
