A properly done conduit rough-in can be wired just as easily with

Where are you that residential conceled wiring is done in conduit???
The only time conduit is uded in residential wiring here in Ontario is
for exposed wiring, particularly unfinished basement and garage where
wiring is exposed top possible damage, unfinished ceilings where
someone may hang things on it, or in steel studs (occaisionally)

Chicago and the majority of its suburbs require steel conduit. Even
if your town does not require conduit most homeowners here insist on
it or the builders just use conduit anyway, its the norm, so few
builders (even if they could) use romex.
