Honestly, I bought a home gym because I did the math. $30+ per month is minimum $360 per year plus the transportation to and from the gym. For about $1000 I decked out my gym with nice gear i got for really cheap on craigslist. Free weights, bench, pulley machines, even mats and racks. My truck was so loaded with weights the suspension was grinding LOL. Decked it out. The laundry room water heater room doubles as the gym.
As others have mentioned, the idea is to make it more expensive for people, so that fewer people will do it.
> Do they assume everyone has a home gym
That's the propaganda version of the "mislead wealthy." Don't be so naive as to assume stupidity where malevolence fits perfectly.
