This is a funny article.
Others have mentioned that it's a little murky if the author is critical specifically of balloon framing or of stick built construction in general.
The irony is that balloon framing is more feasible today than ever. Balloon framing downsides:
1. Really long dimensional lumber
2. Fire risk of continuous cavities
3. Ledger/joist connection to balloon studs
The solutions?:
1. Engineered lumber. Dead straight and incredibly strong LSL (laminated strand lumber) and LVL (laminated veneer lumber) come in basically whatever length you reasonably need them.
2. Fire blocking is well understood. Insulation materials like mineral wool can further drive fire risk inside a stud cavity to near zero.
3. An innumerable number of well engineered and reasonably priced structural fasteners and metal connectors with well understood properties make it straight forward to build a second story floor off of balloon framed studs.
2022 is a great time to be balloon framing. In fact, you'll see it in large great rooms for floor to vaulted ceiling walls. Some framers who like to preassemble as much as possible on the ground and then lift the wall for efficiency and safety will balloon frame as well.
