Earlier quoted context omitted.
You aren't just buying an indoor "replacement" of an outdoor activity. You are also purchasing a coach/work out buddy. It's this latter part that is the differentiator between a normal indoor trainer/treadmill and what Peloton sells.
Right, because treadmills are exactly a boring replacement for an outdoor activity, and you need to augment that to convince people it's different and you should consoom their version.
It's perfectly reasonable to believe that there must be people for which treadmills are incredible.
I like riding and running outside, sometimes really early in the morning when the sea is good for surfing. But I can understand people who would consider the few miles I have to run or ride to the beach utterly boring to ride or run a few days a week.
Other than the different asshole drivers trying to kill me from time to time, there isn't much variety in my outside rides tbh. I can understand someone preferring riding a Peloton bike under nice air-conditioning, with their favorite music in the background, under the watchful eyes of their cat, while watching they kids playing outside.
