What だってそうだろう means here?


From Oshi no ko ch. 1,

After getting stabbed in back, the doctor recalled two questions: "what if you
were born as an idol's child?" and "what if you have looks and connections
from the time you were born?", which he never gave a serious thought before.

I have doubts about how だってそうだろう is understood here. I initially thought it
meant "but I am thinking about it right now" but when I check translations, it
is actually understood as "I mean, why would I?" Which one is correct?




The official(?) translation is correct.

  * だって can be translated as "after all", "(It's) because", "come on", "you know", "hey", "I mean", etc., depending on the context. It's used to convince others by giving a reason. It can be translated also as "but" when you're trying to argue back and convince others (e.g., だって見たんだ "But I saw it!"), but it's not a generic "but". See also: [Why can だって have so many meanings?](https://japanese.stackexchange.com/q/43239/5010)
  * そうだろう in a context like this is "that's natural", "that's obvious", "that's how it is", "I knew it", etc.

So a simple translation of this would be "After all, it was natural (not to
think about it seriously)". I believe it's also correct to translate it as "I
mean, why would I?". It captures the nuance of the sentence very well.
