Why would a buffer be important to homeostasis?

Does not homeostasis entail #"stability in the face of change?"#

Explanation:

And as you know buffers work by preventing gross changes in #pH#. See here for an account of their action. Depending on the capacity of the buffer, #pH# is restricted to a value tolerably CLOSE to the #pK_a# of the acid.

The buffer equation tells you this:

#pH=pK_a+log_10{[[A^-]]/[[HA]]}#

Changes in the concentration of acid or base are moderated by the logarithmic function.
