No problem. I can't comment much on the initial comparison between tablature and fingering since I don't read tablature or more than the very basics of guitar.

It is true that if you map in the reverse direction, tablature can represent playable music even if it's not particularly expressive, while piano fingerings can not. (Well, I suppose you could write music with only piano fingerings and let the performer improvise, but I'm sure that's not the point of this discussion :)
