Why don't you have a flatting range?

Wanted to let someone else reply first before I weighed in cos I was the one debating it with you
I don't see how we can not have a flatting range here. If UTG/UTG1 is/are nitty (and I know one is cos I saw the aliases in original HH) then there will deffo be hands where if we 4bet we are turning them into bluffs but they're too strong to fold.
For instance it's setting fire to money imo to cold 4b/GII v the super nitty reg UTG with AKo and I wouldn't wanna 4b/fold it v him either, nor would I wanna just open fold. No option is that appealing v that villian in that spot tbf but calling has to be better than anything else.
