That's because neither you nor I have presented a model of computation
that manipulates geometric representations.  Maybe it can and maybe it
can't (it will always have to terminate with an approximation if it is
to meet the usual definition of algorithm) but if it can't it won't be
because it's limited to something you once called physical
representations.

No, the requirement you have to drop is for a perfect answer because pi
has no perfect finite decimal representation.  To get a finite answer
you must ask for some specific precision and then the "geometric computer"
could produce it using its representation of a perfect circle.
