Mac Touch ID - Applicability?

[ZipZap]

Why doesn't the user get to decide when Touch ID should be used in place of a password. For example, when I boot the Mac, I dont want to type my password in...I have a Touch ID for that purpose, yet it does not work.

Same as on iOS. Sometimes you have to authenticate with passcode or password to reenable Touch ID / Face ID.
Two advantages:
1. Added security, because less time for someone trying to spoof your fingerprint or face.
2. Added safety, because you're not as likely to forget your password or passcode when you still need to enter it on a regular basis.

The frequency and circumstances should be configurable so i can decide on the level of intrusion protection I want.

Because Apple designed it in a way that doesn't provide the consumer with much choice.

TouchID data is stored encrypted in a Secure Enclave. Your password gets you into the Secure Enclave. After that, TouchID gets you in to everything else.

Well, and the folks at Apple decided it should be the way it is. You may write them an angry letter if you will.
