ᐅ Is it practical to have a utility room located beneath the house?

Please don’t be upset, this question isn’t of practical importance; I’m just curious and hope this forum allows room for such questions.
I’ve heard in passing and have been thinking about it that "in the USA," houses often have a small crawl space (not a basement) beneath them where flexible pipes for water, sewage, etc., are located. If you want to change the layout of the rooms above, it’s apparently very easy because the pipes under the house are freely accessible and can be routed into any room as needed. It seems a bit more complicated here in Germany. Do you know why that is or what disadvantages this American-style construction might have? I saw this on the TV channel HGTV, which features many home renovations.

It’s all so misleading. You are right. Polystyrene, adhesive, plaster powder, paint are produced, transported back and forth, applied to house walls, resulting in two identical houses—one with an external thermal insulation composite system (ETICS) meeting KfW 55 standard and the other next to it in the original condition—consuming only slightly different amounts of gas. This can be found as an experimental film in the ZDF media library. And this is how we save CO2...

And that’s how we save CO2... First of all, I would be interested in that ZDF report or at least the boundary conditions; unfortunately, I can’t seem to find it.
Secondly: WHICH insulation material you put on your wall is entirely up to you. It can be polystyrene, but it doesn’t have to be. And the overall environmental impact of ETICS (especially regarding demolition and disposal) is controversial, that’s no secret, but ETICS is not the only option for energy-efficient refurbishment of older buildings.
And you (or rather the ZDF report) really want to claim that a completely unrenovated old building (for example, from the 1960s, with 24cm (9.5 inches) brick walls, an air cavity, and 11.5cm (4.5 inches) facing bricks) compared to a renovated house (24cm (9.5 inches) brick wall, 180mm (7 inches) insulation, plaster) does not save any energy? Or is the comparison actually between a house with minimal insulation standards (1980s) and a better one? In that case, I agree savings would only be minor.
However, we’ve now drifted far off topic here; perhaps it would be better to continue the discussion elsewhere if desired.
Okay.. I’ve been reading the comments below for quite a while, it’s very entertaining.
But the main point of the video is simply that thermal insulation is useful, but only in moderation. It should be clear to anyone with some basic understanding of physics that the first 10cm (4 inches) improve performance more than the 11th to 25th cm (4 to 10 inches).
