Yes!

Most of Europe has a "registered building" system, where buildings above a certain age are considered historic. Renovating those buildings is an extremely difficult, expensive, and bureaucratic process. You generally need to preserve the period-appropriate look and materials. An AC unit sticking out of a wall won't pass muster.

Even newer buildings are problematic. an acquaintance of mine lives in an upper-middle-class apartment complex that was finished two or three years ago, and their architect has some claim in the contract that prevents residents from installing AC units to "preserve the building's unique look."

The US is build around privately-owned housing (and hence creature comforts) a lot more than we are, so AC is a lot easier to implement there.

If you rent the place and your landlord doesn’t want it you’re out of luck. If you own the place and your neighbors don’t like the noise of your AC you’re out of luck too. If your building is one of the many buildings protected for historic reasons only God can help you.

That's not the only thing required to properly install an ac unit. Do you genuinely believe people die rather that drill a hole? Lile that's the blocker? What a weird take
