About ないことには～ない

ないことには～ない is a 2-part structure in Japanese that is used to express that 'unless you do (A), (B) will not happen or exist'. This is a combination of ない, こと, に, は, and then something followed by ない in the (B) part of the sentence. Literally, it just means 'within the situation of (A) not being a thing, neither will (B)'.

This structure may appear with verbs and い-Adjectives in their ない forms, or nouns followed by でない.

In sentences that use ないことには～ない, (A) can be considered the condition for (B) being able to occur or proceed.

Caution

Occasionally, ないことには will be seen in sentences that do not finish with a word in the negative form. In these cases, ないことには implies that not being in the state of (A) will negatively affect (B). This translates similarly to 'without (A), unfortunately (B)', and often has structures like しまう following (B).

Just thinking… Is this point somehow related to なくてはいけない? Sounds like they could be related. Like this…
～ないことにはいけない
～なくてはいけない

Am I correct in thinking that this structure could be boiled down to simply ないと?

For example, the first review sentence is「夫婦では仲良くしないことには、うまくいかない。」but to me, you could just say「夫婦では仲良くしないと、うまくいかない。」and it means the same thing. The second review sentence,「やってみないことには、出来るかどうか分からない。」similarly could be said「やってみないと、出来るかどうかわからない。」and carry the same meaning to me.

Obviously this isn’t the first or last time there’s many ways to say the same thing, but is this a correct assumption? There was nothing suggesting ないと in the related grammar section of the lesson.

According to the grammar point for なし, the word/vocab 無し (なし) is equivalent to ない事 (ないこと):

About なし

Although it is used almost exclusively as a suffix, なし is actually a noun that means ないこと ‘thing without’. …

So, that would seem to imply that this grammar point, ないことには～ない, would be equivalent to a similar (identical?) hypothetical grammar point なしには～ない. Is that correct?

Because when I checked on Jisho, I found several sentences for なしには (sentences), and they all followed the pattern of ending with a negative, i.e. なしには～ない.

Is this correct, that ないことには～ない is equivalent to なしには～ない (simply because なし is equivalent to ないこと)?
