It's the government trying to enforce their opinion of who should own those Bitcoins, thereby taking power away from the owner that the network has decided on, which would be "whoever has the cryptographic keys".
A person can believe whatever they want, but when push comes to shove, it's a country's court of law that ultimately determines who legally owns what.
I think you've answered your own question - a true crypto believer does not agree with that. If the smart contract says the Ethereum is mine because you wrote it poorly and I called the transfer money function in the right way ("exploited it"), a true believer would say "yep, it's yours."
