Professionals aside, any self respecting DIY store will readily sell you masonry drills in lengths suitable for most walls. And in the rental section, you’ll be able to get a core drill plus the appropriate machine (exactly the kind of equipment professionals will use for big holes in thick walls) for making any hole too thick and/or too deep for a regular drill. Since core drills can be extended, your drilling depth (for practical purposes) pretty much is only limited by the number of extension rods you have available.
I don’t see any problem, most professionals have suitable material to drill through wood, brick or concrete, to thicknesses of 1 m.
Probably difficult to understand for people who live in houses with cardboard walls.

I fully agree with your explanation.
A thick wall penetration of more than 1 m requires some experience and respect for safety.
