Yes, that is because if you have the time and $$ to have hobbies, you move above Maslow's Safety Needs level (see below) and starting spending money/time on much fluffier stuff!
As a 12 year old paperboy delivering newspapers on the bike I built out of bikes that grownups put out on the curb for trash day, I never considered paying for special socks to bicycle in! Let alone upload my mileage each day to some site that would show me that the paperboys for competing newspapers were faster than me ...
(Two clues in the above that I am an old goomer: (1) The term "paperboys" and (2) the idea that there might actual be "competing newspapers" in one town.
It isn't a hobby until you get above the Safety needs level...
