In the grammar explanation for なりに on

ninari-no/), I ran into the following sentence:

私には私なりの理由があっての事だったんです。

I am curious about one part in particular:

があっての

Is this any different than がある? I know の makes it so that あって describes the
following noun instead of the following verb, but why not just use がある instead
— which already modifies a noun by default?

The one reason I can think of for using があっての is in conversation when the
speaker is not yet sure what they will say next and needs to tie the って to a
noun. But I am unsure if this would be the main for using or if this would
work with every verb.

Difference between っての名詞　and る名詞
あっての emphasizes the prior phrase as a reason, without which the following
phrase could not be. Please see
[here](https://www.mlcjapanese.co.jp/n1_04_15.html) for other examples

がある would not make much sense here as a modifier of こと。You could say
私には私なりの理由があったんです, but it is not as strong an utterance.

answer
The following four sentences are all grammatical. I would like to discuss
these only in this context.

  1. 私には私なりの理由 **があっての** ことだった **ん** です。
  2. 私には私なりの理由 **があっての** ことだった **ん** です。
  3. 私には私なりの理由 **があっての** ことだった **の** です。
  4. 私には私なりの理由 **がある** ことだった **の** です。

It can safely be said that sentences 1 and 2 are usually heard in conversation
because of ん, not of あって, but 3 and 4 are a little more formal, which can be
used in spoken and written Japanese. But it seems very difficult to find
slight difference between 3 and 4. In the sentence 4, the speaker (私) is fully
aware of his own reason, while the sentences 1, 2 & 3 having あっての may imply
that even if the hearer may not know his reason, he has his own reason. The
use of a little indirect expression あっての might make the speaker avoid
criticism or something from the hearer. This is my opinion or feeling, but
others may feel in other ways.
