My main critique of Einstein's text is about the use of the term 'space' 
in it.

'Space' denotes very different things.

In real word cosmology, we use the term 'space' as name of what is 
outside of our own realm on Earth.

But such a 'space' is actually an image, which we receive from the past, 
hence unreal.

So, what we see in the night sky is not real, but a very distorted 
picture, which is not even internally consistent.

A more 'natural' space would be Newton's absolute space. But, 
unfortunately, that space is invisible and Einstein rejected it 
existence, anyhow.

Another use of the term 'space' stems from mathematics, where the span 
of n linearly independent vectors is called 'space'.

Now we need to pick the appropriate mathematical construct, which would 
behave like physical space.

In such a space a physical point has a position in a coordinate system, 
which could be described by the position vector of that point.

But this would not make physical points equal to position vectors. The 
position of a point is only one of its features, but not the only one.

No.

Actually you call 'incorrect', what is a very trivial consequence of the 
used settings.

We have two coordinate systems (K and k). k is moving with velocity v 
along the x-axis of K.

Therefore

x_0 (= zero spot of K) and xsi_0 (zero spot of k) are related as

x_0 +v*t=xsi_0

Meant with these variables were not points or vectors, but the numerical 
values of the scalar components of position vectors.

Hence to any coordinate value in k I can simply add v*t and get the 
coordinate values of the same point in relation to the korresponding 
system K.

Since the variable x' means the coordinates of a point in k, but 
measured with coordinates from K, we can simply add v*t to the 
coordinate of the mirror in k, to get the coordinate values of the same 
point in K.
