You are.
Time.
You responded to a post written BEFORE the world position option was added.
Remember, the forum is a place that is written based on the current rather than the unknown future.
Our complaints meant BL added the option.
They still do not allow setting a z-position to any object. Any object with a positive (floating) z-position MUST be part of a group (merged objects).
There are times when being able to set an object to a height above the build plate is needed, but it is currently not possible without hacking things.
