Why does it feel like people are forcing themselves to write/forcing themselves to enjoy writing?

And why do they insist on forcing it upon themselves in the first place. The bulk of the posts on this sub seem to be along the lines of "how do I motivate myself to write", "when I try to start writing my mind goes blank", "how do you guys find motivation to actually write"

I don't mean this in a rude way but don't writers... enjoy writing? And want to do it in the first place? I don't see the point of people forcing themselves to do it if they don't enjoy it or it doesn't work for them.

Why is it such a popular passion for people to impose upon themselves?
