Between the OP, your post, and @ketopian's below, I think there's a pretty complete picture forming.

I note where you write:

People come on here believing it's something they want to do because they also have opinions or whatever, and the money is a good incentive. But when they realise the money isn't an incentive, they simultaneouslly realise they actually hate blogging.

Yet ketopian highlights how they don't HAVE to blog here. They could post FB content here, and some people do.

The issue in all of this is a combination of 1) Expectations; and 2) the Social Factor.

Expectations people are attracted here with are usually about money, so people do grade the experience in those terms. Yet we all know how long and hard we have to work to earn money here. And that we have to include the Social Factor, which many don't at all, not realizing that they need support from people to succeed here financially, and that they also WANT support from people beyond just money.

The social factor is that if you have support from people with enough SP, you'll make money on here, but will you have fun?

Will you have meaningful comments and relationships that grow out of those?

If you start on here knowing no one, then Discord is probably the best place to start the ball rolling on getting support and finding people interested in things you're interested in who are willing to get involved beyond just posting.

Searching by tags (instead of using trending) and then commenting on posts with active comments sections and a responding OP is also a good way to start the social game. I credit much of my early traction on here to finding great people to follow early on then leaving very meaty comments on their posts, comments they wanted to engage with. Over time they wanted to also see my posts, and the game was on!

But another part of the social factor is that people downvote here. And when they do, if they have enough money/reputation they take away some of your money/reputation. And they can post mean things about you too, ridiculing what you do.

I mention this because while you CAN post quotepics and one-liners on here like on FB, if you do you're likely to be punished for it by those who feel the platform SHOULD be a quality blogging platform.

Thankfully there are other steem dapps besides steemit. You can just leave a quotepic on something like dLike, I believe. You can just drop an image on steepshot. You can just upload a video to dtube, with maybe a sentence of description so someone knows why they're interested in watching it. And so on. Having to write long blog articles is apparently a steemit requisite, but not a steem one.

However, needing to socialize off and on the platform to build relationships is a requisite for success. Even if you buy a lot of steem to power up, you still won't find this a place you actually want to be if you don't form a community around you or join one. Because we are all social beings. I don't think anything is wrong with that, other than an unwillingness to accept it and adjust accordingly.
