Is it sufficient for the theoretical physicist to utilize 3D space
because it is observed or is the theoretician supposed to explain the
observation? In the past such a situation was probably considered
beyond us, but with the advent of string and brane type theories this
opening exists. A traditionalist might see this as digging beneath the
ground level and so perhaps we are studying the roots of the great
tree. The underground is radically different and to those who stay
above ground it is an invalid space. Yet something must keep the tree
from toppling.

True enough, but conversely why should the underlying reality have to
have dimensions? Also, why are three dimensions sufficient for us in
our day to day lives?

Mostly because we're actually real.
