True enough.

But then you have to decide whether there's anything
"fundamental" about SI. IMHO there isn't. SI was
chosen, and it could have been chosen differently.

No doubt! I didn't thought for a moment that it could
be different. I assumed that "fundamental", here,
meant "not derived".

Best wishes.
