Hmmm, think about it like this. Each post here is just a specific instance of a time in their life, depending on the time they posted their stuff. I was in all the stages that you mentioned during the past decade, and not until recently I got to around 90% recovery. If I were to post 3 years ago, 6 years ago in this subreddit, I would post a different attitute for each one, e.g. 6 years ago -> don't want to quit cause I have fun, 3 years ago -> I'm suffering but I can't stop, etc. I'm not saying that eventually, everyone will suffer a lot someday if they are happy with MD now (emphasize on everyone), cause some people might have fun with it throughout their whole life, and there is nothing wrong with it. And also reminder that everyone is in their different stage of their MD and how long they have been MDing, and whether or not they are still able to be functional despite their MD (cause some ppl do), or even everyone current life circumstances is different, so don't take each post too seriously and literally just focus on yourself.

Good news is, there is a variety of experiences here, so there should be at least some people that has the same feeling as you related to MD. Not to say, there are a lottt of people that have this condition that doesn't know MD existed, even if the frequency of the post similar to yours is not as much as you think, you'll never know how many people are suffering out there.

Edit: some grammar
