You are dead on with the point about the instructors. My wife hated biking but they have Pelotons in her work gym, and she loves them, and talks about the instructors like they are real people.
People are fitness crazy right now. Crossfit gyms are $100-200 a month, Rogue has whole website of fitness equipment, you could easily spend $4,000 outfitting your house. And how many of us own a $600 blender?
