Looking for an explanation of the usage "あったものじゃない”


I'm looking for an explanation of the usage "あったものじゃない”.

例文

> １）ムードも何も **あったものじゃありません** ね (context:Girlfriend and boyfriend were out on a
> date and the boyfriend's stomach made a large noise because he hasn't eaten
> all day)
>
> ２）心の準備も何も **あったものではない**
>
> ３）美しい景色も何も **あったものではない**

Looking at these expressions in context they seem to strongly deny the part
before も何もあったものではない, but can someone explain the way the grammar is used here?




My true feeling is that the expression 「～～も[何]{なに}もあったものではない」 should be
memorized (and actively used) as a common idiom than be analyzed
grammatically.

> It is an expression of "total" negation. "There is no ~~ whatsoever!"

「～～も何も」 lumps together things that are like or related to "~~". See

「あった」: Do not take this to be the past tense. Rather, take it to be in the
hypothetical form because with this phrase, you want to say "~~ could not
exist." **You are only stating your opinion; You are not stating a fact**.
What I mean by that is that 「あったものではない」 is **_not_** an expression about
something that actually existed, exists or will/might exist. In that sense, it
is tense-free to begin with.

A better-known expression for J-learners would be 「～～した方{ほう}がいい」, which is
also an expression for stating an opinion rather than a fact. People often ask
"Why use the past-tense た?" in it, but again, that is NOT the past-tense た.
**The speaker is only giving advice; It is only his opinion**. Just like
「あったものではない」, this is not an expression about someone actually doing something
in the past, present or future. It is "tenseless".

「もの」 here is a nominalizer with a special function to express one's judgement
emphatically. See Definition 5-ア in
