Ok, but how long is a meter? If you define it as 1/299782458 of the distance light moves in one second that means that as your experimental procedures improve and you know the exact speed of light better the length of a meter changes.
You can't define everything as you wish and remain consistent. In the last century the Indiana state legislature tried to pass a law decreeing that the exact value of PI was 4. It missed becoming law by one vote, but probably wouldn't have worked anyway.
