That would still be quantifying values against the tangible axes of time and/or money. There are still various other intangible factors such as happiness, goodwill etc which are immeasurable, yet contribute to the overall picture.
No, not "definitely". You are assuming they are because "reasons". However, we have no idea whether those "reasons" apply, or whether they mean something is measurable.
You may have an argument that they should be measurable, but that's a far cry from "they are definitely".
A little humility is a Good Thing™
We have no good evidence so far to believe in magic.
Everything is definitely measureable? How did you solve the Measurement Problem? It seems to have all the other quantum physicists stumped.

The problem with saying "everything in reality is physical/material", is that we don't even know what that is on a quantum level.
It is however a license for doubt over certainty.

Once again, no one is sure about this.
