You talk about "approximability" without giving even the
slightest hint what you mean by it. This is not a base for
any fruitable discussion.

Approximation is not a well defined notion. It has
 different definitions in a lot of different contexts. The
quality of approximations is an even more complicated issue.
There are some functions which can be approximated well,
there are others that provably cannot. I don't know of any
general notion of approximability that allows for arbitrary
accuracy approximation for any definable functions.
