there are purely mathematical definitions for most SI units now.

Physicist here.
Mathematics CANNOT be used for defining natures constants.Simply because these constants are the bridge between nature and mathematics. This bridge must be rooted in BOTH nature and mathematics.

This is why the pound is superior. In America we just use a pound of silver to as the standard.

"The metre is the length of the path travelled by light in vacuum during a time interval of 1/299792458of a second."
Speed of light seems pretty constant, am I missing something?

So, this relates the meter to the second (both natural phenomena) by a number.
Nature: second, meter
Mathematics: 1/299792458

but the second also has a mathematical definition: "The time needed for a cesium-133 atom to perform 9,192,631,770 complete oscillations."

So again, this links both the meter and the second to a cesium atom.

In this way, the Cesium-133 atom is kind-off THE standard.

Certainly, this is not purely mathematics. There is some mathematics and some nature in these definitions.
