I think it's a great analogy, but then, I've been playing poker for fifty years (just realized, wow, I am OLD). As kids, we played 5 card stud and blackjack (21) using toothpicks for chips. Parents let us play 'for fun'. But I digress. Back on topic ...
Playing poker for fun very quickly palls. For a while I joined in a once a week game of 7 card stud, sit down money £10, once it's gone it's gone but you might win 50 quid,
However, it's not enough. It has to hurt a little bit if you lose and feel good if you clean up. So now we play once a month, sit down money £50. That means £250 possible winnings unless you fold the game early.
