Perhaps I'm dim, but I don't really see the problem with
measuring the speed of light.

First fix an arbitrary length to be your unit of measure and call
it the meter.  Then measure the distance traveled by a beam of
light in C ticks of the cesium clock.  You will always have the
standard meter and the cesium atom to refer to later...  in the
same way that you use light beams to gauge the value of c, the
speed of light.

Both C and the meter are arbitrary, but always constant when used
wrt the value of c.
