Keep in mind that the memes you see are extreme examples. The vast majority of compound words consists of 2 or 3 words. Like Ofenreiniger (oven cleaner) or Werkzeugkoffer (tool box). Werkzeug being a compound word itself, made from “Werk” & “Zeug” meaning craft or work & gadget. These extremely long words tend to describe very specific, often niche items and are just rarely used in common language. Most people would call the thing in the picture more generalised “Feuerwehrauto”. Sufficient to describe it for most people, but not as precise as the long compound. It is basically a question how much details you want or need to communicate.

Body odour is - thanks to deodorant - very much a choice.

You are right, air travel is no fundamental right. Same as air travel in complete silence.

What about ugly people or people with body odour? Do we not allow them to travel on planes, too? I can easily block noise with earplugs. Can’t really plug my nose or keep my eyes closed all the time.

Why is everyone else responsible for your comfort? Wanting all families banned from airtravel just because wearing earplugs is asking too much is in my opinion a lot more selfish than bringing a child onto a plane.
