Every custodial solution requires guarantees. Legal enforcement is one kind of guarantee. If we are to obsolete the government, we need a cryptographic self custody solution for ecash. Without one, it will require compliant companies like Strike to operate a mint. It may be impossible to operate a legitimate Chaumian eCash mint as a money transmitting business under current laws given blind signatures prevents KYC, and mints facilitate transfer of fiduciary media. That leaves us with anonymous mints, under which a rug-pull can happen at any time. This is where a cryptographic bond may be useful, one where an anti-rugpull guarantee can be enforced by loss of an equivalent amount of bitcoin if the token holders can prove the mint is unwilling to redeem tokens.
