childfree means, that im not getting a kid despite my instinct, i decide not to have any. by doin so i dont repeat the "no money, no time" struggle my parents had.
many also say that the current state of the world is not suitable for a little one. bit of a doomer thinking, but i do accept it as a correct anwser as well.
the "hehe look at all the freetime" is kinda a funny comic strip like state of mind. it is def an advantage, but never a main reason. at least not if you are not an egoistic shithead.
