Not carrying an ID card? No access to anything - public transportation, payments, and can’t even authorize your car to start. Also, it’s a felony to do so intentionally and with intent to evade law enforcement monitoring.
State wants to search your laptop? Your 2FA and disk encryption is mandatorily tied to your ID card, and the state holds keys in escrow.
Some things should be onerous for the state and decentralized. This is absolutely one of those things.
