What does それ refer to in それでいい in this exchange?


「ええい、御託はいい！！それより流星。お前は見たくはないのか？嫁達の喜ぶ姿を。」

「嫁達の喜ぶ姿…」

「しかも温泉で！」

「お、温泉で…」

「…わ、分かった。嫁達の健康と笑顔には変えられん。」

「ふははははっ、それでいい、それでいいのだ、流星！」

In this exchange I'm a bit confused as to what the それ is actually referring
to. In this conversation they were trying to convince him to go with him and
the 嫁達 to a 温泉 and after much persistence(other stuff before this part of the
exchange has been removed to keep it short) he eventually gives in and gives
the excuse/reasoning 嫁達の健康と笑顔には変えられん. Now normally I'd think that それ would
refer to the actual utterance itself but I can't see it literally referring to
the previous utterance apart from the fact that it's basically 流星 agreeing to
what the other person had suggested(i.e 温泉で嫁達の喜ぶ姿をみたい). Can anyone explain
exactly to what それ refers to in this situation?

edit: Does it refer to 流星's desire (温泉で嫁達の喜ぶ姿をみたい) Does it refer to 流星's
acceptance of his idea Or what does it refer to?




「それ」 here does **_not_** refer to an actual utterance made. Instead, it would
refer to 流星's logic, reasoning or way of thinking that has been expressed by
the line 「…わ、分かった。嫁達{よめたち}の健康{けんこう}と笑顔{えがお}には代えられん。」= "Alright. Nothing could
replace our wives' good health and smiles.".

「それでいい」 often means 「その考{かんが}え方{かた}でいい」 or 「そのやり方でいい」 and this one is no
exception. It is an expression of approvement of another person's action or
way of thinking.

It is kind of close to **_"Way to go!"_** in feeling.
