As opposed to fiat that will steal somewhere between 3% and 300% of the value of your assets every year (depending on your jurisdiction) and deposit them into someone else's account?  Fiat and other systems that are subject to the whims of someone else (not censorship resistant)?  When the former US President with billions of $ is shut out by Stripe and PayPal and certain manufacturers are shut down by credit card companies, censorship resistance is critical.  That's why the CCP and other totalitarian and authoritarian (fascist, communist, socialist etc) rulers around the world don't like it (see e.g. the current US President, Joe Biden, and much of his party) - they want power and control.
