We say that, but how much time to people spend just watching TV or Netflix? All of that is "free time". People just spend it without thinking and then lament their lack of free time.

Then what you're really saying here is that you think they're spending their free time wrong. Maybe they enjoy watching Netflix or playing games or whatever much more than you enjoy your zen moment of washing dishes and listening to the radio?

It's like me going for a Sunday ride on my bike (which I very much enjoy) and then telling other people that they shouldn't resent having to commute to work in rush hour every day.
