Not using the correct pitch "spellings" means that the chord stackings
lose their "functional" character. You stop being able to see at a
glance whether there is a seventh or a sixth, for example. That's bad
on an instrument like the piano since you lose the connection between
the expectation of a particular sound and its execution, and it's worse
for an instrument like the accordion where particular chords are
produced by pressing particular buttons, like Cmaj7 as c (major) and em.
If you cannot see the function of a chord, figuring out the button
combinations is close to impossible.
