Just playing devil's advocate . . .
Are we to understand that, even though a melodeon is capable of playing more sophisticated* music that straight up and down the rows D/G stuff, we shouldn't?
I wouldn't take up the accordion to play "loads of chords" - I actually enjoy the limitations of the melodeon and, like many others, I like pushing against the boundaries. Surely its' limit has been reached when there is absolutely nothing else to be learnt or played.

* I mean technically sophisticated - I actually think that most traditional music has its' own inherent sophistication which belies its' deceptive simplicity.
