Yes.
Each of the extra blocks has data and I had done the same as you suggested, testing each one to see if it was visible in the diagram. That is how I found out they were extra, and were created by the program somehow, since i did not make them.
Yes removing them all greatly reduces the file size, which is why it is important for me to delete them, since the other quirk of LibreCAD is that very large files will not permit selection of an object.

I did not have the same experience as you when copying and pasting the desired elements to a new drawing. For some reason I just get all the layers and just one block copied (0.5-tab). As you say the copy-paste thing does not really help me much, since I have to recreate the diagram through the copy paste routine; which in my case does not re-create all the needed blocks anyway (version and OS issue?).

My actual issues are:
 1. not understanding why the operation of LibreCAD finds it necessary to create unused copies of an existing block, and
 2. assuming it is necessary, then being able to efficiently delete the unused duplicate blocks (already determined to be outside the scope of LibreCAD development)

Thank you.
