That only works if you live in a paper house. Drilling through normal brick/concrete walls is not that easy - we do call someone when we need our wall mounted TV setup.

I doubt you live in a house where every single wall is brick or concrete. Unless you live in a nuclear bunker.

I live in a concrete building, and only the exterior walls and one or two interior walls are concrete. The rest is normal walls that for some reason you refer to as "paper." I guess they don't have lumber in your country.

You're just inventing problems where none exist.
