You should regard measurements as human artifacts and totally irrelevant for nature.

 So are "quantities", unfortunately.

Actually I make the distinction between measurement and quantity.
So: we have, say, a stick of e.g. wood. This has a certain form, which we measure in -say- meters.
Now the real thing 'stick' has an attribute, which we call 'length' (or 'form' or whatever you like).
But this stick has this attribute without human intervention and whether we measure it or not.
The measure 'meters' however and the measuring device are human artifacts and belong into our own realm and would not exist without us.
Therefore the measurement is an artifact, while the quantity is a real attribute of something we measure.
The 'cut', however, between the stick of the example above and the tree it still belongs to, is an artifact again.

 

We can measure something, however, and did so since ancient times.

 Nope. "length", "time", "energy", anything -
are human developed abstracts.
 

If you say essentially the same, you should not write 'nope'.
