I've never really seen the point of cluttering ones brain with information which is readily available on paper (excepting information vital to your function in life).
Music scores are written as an expression of the authors wishes and it is only polite to implement them. They do allow a player to sample all kinds of stuff..just like a library..and you don't have to own it in memory to use it.
For ensemble playing; in my experience Barn Dance bands play either one tune specific to the dance - most Playford dances - or a medley for rumpty-tumpty dances written out so that changing band personel from week to week does not affect group performance. I would expect that to apply for all genres.
So why hunt and peck when you can get it right from the start?
On the other hand, if you like session playing using the same tunes over and over again, learning by rote seems the only sensible option.
