BTW: High trees often doesn't cover land, the grass (or bushes) below does.
How do you tag this with landcover?
let's say they don't cover the land on the surface, why surface is not
a good tag.

You didn't answer my question.
How do you handle "conflicting" grass and trees using landcover?
Natural is IMHO an ideal example of a tag to diffuse
clarity and create confusion, because it is a mix of all sorts of
features.
It contains features that naturally appear. I am not confused.
fine, I got this, you don't care for semantics or content of tags, of
what the do express, if they are grouped with a certain sense or not.
They *are* grouped in a specific sense. Already. Today. It's just that
you don't like that group because it doesn't fit into your mental model
how it should be.
Of course you can make a group natural with all natural objects, but
natural is not even this. There are other natural objects that are not
in natural, natural is simply a mixed collection of geographical
features, physical objects (few) and different others. I'd like to
reduce it to geographical features (coastline, bay, beach, cliff,
....) and find a better place for stuff that doesn't fit into this
logic.
You simply want to change the existing logic that you don't seem to like
with a logic that you like.
I perfectly understand what you are trying to do, but I simply disagree
that it is a good idea.
The only reason you are not confused is that you took part in the past
years of mapping in OSM and therefore you know all these values by
heart. This has nothing to do with logics or a systematic approach, it
is simply sticking to traditions and definitions in the wiki.
It is accepting that semantically different things can reside under the
same key and that this doesn't cause any problems - except for people
like you that seem to think that a systematic approach is a value in itself.
It is also knowing that remembering six different "semantically correct
groups" each with their own key are a lot harder to remember than two
keys containing easy to remember groups of values. May look nicer if you
draw it on a piece of paper, but doesn't work well inside the human brain.
On one hand it is fine to let tags evolve, everybody uses those tags
he likes, etc., but after a while there should also be some
reflection. There should be the possibility to question concepts and
make changes. Otherwise it makes mapping and extension of the tagging
system simply harder for everyone.
Fine. But people wanting to change existing things should have and being
able to explain good reasons.
