How would you express "A demands B" in japanese. In the sense that 'demands'
is being used as a synonym of "absolutely requires". But using this expression
instead of "requires" has a nuance. To me the nuance of this expressions is
slightly refined or authoritative, or even elitist.

For example, a luxury car commercial: We see a close up of shiny curves, the
voice over says,  
“New thinking demands bold designs".

Other examples might be;

'creation of the new demands destruction of the old'

'poverty demands action'

'quality demands time'

and so on.

[edit] Looking at side by side corpses I came up with:

A は B を要求します

And Then I was advised that IT was better to say:

A には、 B を必要とします。

or

A は B することだ。

But I'm not sure if the nuance is conveyed.

How would you express "A demands B" in japanese
The subject of 要求する usually has to be a human. When the subject is an
inanimate idea, "A demands B" is a typical
[物主構文](https://japanese.stackexchange.com/a/32449/5010) ("thing-as-a-subject
construction") sentence that looks fairly odd to the eyes of Japanese people
if translated too literally.

AはBを必要とする and AにはBが必要だ will look far more natural. If you need the nuance of
"absolutely", you can use
[不可欠](https://jisho.org/word/%E4%B8%8D%E5%8F%AF%E6%AC%A0), 必要不可欠 or
[必須](https://jisho.org/word/%E5%BF%85%E9%A0%88) instead of 必要.

>   * 新たなものの創造には古いものの破壊が不可欠だ。
>   * 貧困に対処が必要だ。
>   * 品質の向上には時間が必須だ。
>

(For the first one, I would prefer a free translation like
新たな発想は大胆なデザインから生まれる)
