Why aren't biometric data and their use banned?

The use of biometric data has become widespread in my country over the past few years, and this makes me extremely uneasy.

All our health data was hacked because of our government, yet they are still processing transactions using biometric data. We have no right to appeal this, and it makes me feel like it's going to cause irreversible problems.

Given the high risks of using biometric data, why aren't governments returning to traditional methods? If our chip-enabled ID cards fall into the to take of malicious individuals, they can do anything to us, and there are no measures to prevent this.
