Me, who uses it.

The people playing on my server are to lazy ( but still complain if there's nothing to do even though they've only acquired their armor and built a decent base )

It's their fault.

I don't think there's a lack of content, but there's no goal but building ( which can get boring because then after these two weeks no one is playing anymore ) after acquiring armor or building a base. Defeating the Ender Dragon is not worth mentioning because it's just to easy.

You can. There's a Datapack called ,, Batty's Coordinates ", that displays the coordinates above your hotbar.
