Instead of thinking in hyperbole, think in CS terms:
"Solid" houses are "immutable", and "paper" houses are "mutable".
I recently redid some plumbing in my "paper" house. It was real easy: shut off the water, cut some dry wall, make the fix, put some drywall back in, plaster, and paint.
How would this work in a solid house? Do I need to jackhammer through stone and then mix concrete to seal it back up when I'm done?
I've got copper tubing running along the bottom of the walls and going through inner walls and flooring. I can't think of anything going through the outer walls. We've got an antenna cable routed through a window frame.
You don't. You really don't need that for years and years in a row. When you need, you do need some tools though.
I see we can have all kinds of analogies; I guess habits play a big role here. Different places in USA have different house styles - it's a big country.
