Why the false dichotomy? A person could easily lack all respect for an entertainer and still want to go see them... Heck, I've gone to concerts before just to make fun of the band and its fans with my friends. One could be there doing a lot of things but the blindingly obvious answer in this case is that people like to record stuff.
Jack sounds like a vampire. It my energy that he's feeding off of isn't it? Seems like Jack should respect his audiences' wishes.
Furthermore, if the concert venue can't go out of their way to provide a measly fucking digital video and picture download for people, then I say fuck 'em.
If they don't respect my wishes why should I respect theirs???
It's kinda like how HN asks you not to treat the downvote button as a disagree button and to just post your disagreement - but just about everybody ignores that rule because thinking is hard. Hmmmmm
