Don't limit your imagination based on the current bounds of science. We
currently have a myriad of tangible products that, at one time, were
completely inanimate, but because of increasingly embedded processors,
are no longer so. Think books, fridges, appliances, etc., for examples.
So, what was science fiction yesterday is often now everyday reality.
Hence, the fact that currently a common glass is incapable of copying
itself is completely irrelevent.
As to your suggestion that "wouldn't it be more rational to have objects
capable of constructing copies of objects?", that seems to me to be an
orthogonal question to whether or not the receiver can or should be able
to create a valid copy of itself. Both concepts could both be true
simultaneously, both be false simultaneously, or one true and the other
