The notion that performance choices should be made based solely on personal, artistic vision is really cute, but I'm asking more in the context of non-fantasy-land. If only it were the case. . .
On the one hand, of course I'm not suggesting that performance choices should be based on personal musical and artistic judgement alone - and incidentally, here I do think what is written in the text should stand, also since Liszt very well knew how to write rolled chords - but on the other, surely these are what signify one's art!
On one level, if it's not at least partly the case, then I'm afraid you've missed the very first thing about romantic music. On another, I would really like to ask, what, if any, is wrong with personal, artistic vision? Or rather, what is with the obsession among certain musicians concerning "historically correct performance practise" (in keyboard music in particular)? While some have been useful and enlightening, some feels truly pedantic; and yeah, sorry, I do find your question here tending towards the pedantic also.
