That argument ignores the fact of the relativity of simultaneity.  You 
cannot measure the positions of the end points of an object at the same time 
because the information from them does not travel instantly to you; it 
travels at most at c.  What you can measure is the time that a light signal 
emitted from one end point takes to the other and from that, assuming that 
neither end point has moved, calculate the length.

Therefore, nowadays precise distance measurements are done using 
electromagnetic radiation, e.g. with lasers or radar.  For example, there 
are mirrors on the surface of Luna put there by Apollo astronauts, and 
lasers from Terra can be directed at them, to determine the distance between 
Terra and Luna on a given day (LLR).  And the distance between Curiosity and 
Mars’ surface, and the speed of descent, in order to know when to enter into 
each of the phases of EDL, was determined with a radar altimeter.

ISTM you have not read carefully or you have misunderstood what I wrote:

> Not all objects have the same "intrinsic length" ==> useful.

To emphasize what is meant by my previous statement:

That not all objects would have the same “intrinsic length” (i.e. length in 
the rest frame) is irrelevant, because the same objects also would not have 
the same observed length when observed by the same observer in relative 
motion to them (_not_ co-moving with them).

I can see only one caveat: If the difference between the observed lengths of 
two co-moving objects, i.e. after Lorentz transformation, falls below the 
Planck length, an observer would no longer be able to tell their lengths 
apart and would have to assume they are of equal length even though in their 
rest frame they might not.

With the exception of Lorentz-invariant ones, there are no intrinsic 
properties; to assume there were is an illusion.
