I suspect it’s not just you, but you will certainly be in a minority, as this thread suggests.
I assume that you turn your Mac off, rather than leave it sleeping. I have no idea what the proportions of people in the real world (as opposed to macrumors) is regarding this, but even amongst those who turn their Mac off, I think that Touch ID there could be a pain. These things book up quite quickly, but you would still need to be holding your finger on the button for longer than seems natural whilst waiting for it to kick in.
For those people who leave their Mac sleeping, this would be a major pain. On the rare occasion I need to use the power button (usually if I need to reboot after a problem) it takes a while to find it.
That is just starting up. As others have mentioned, authorising passwords and payments would be much less smooth).
I understand your reasons for wanting this, but you are miles out with the cash grab theory. Apple have gone with a solution which is far more convenient for most people, and that seems to be the main reason for making that decision.
