I just finished honing out the seat post lug on my 69 PX-10 after suffering the horror of mauling the post it came with. I was not about to subject a NOS post to such abuse without cleaning up the receiver.
Being the analyst I am, studied it and noticed the assault was made by protrusions at the expansion slot where a previous owner or so called mechanic had tried to spread the clamp with a flat head at the interface of the slot and the post and left indentions distorting the edges.
I wonder if the issue on your bike was from the same type of abuse rather than coming from the factory that way.

It is interesting to me that this professional-grade bike had a flaw that would not be tolerated today. Even kid's bikes have seat posts that fit like pistons these days. My 1977 PX-10LE was also murder on seat posts, and up until a few years ago I just thought having scratched seat posts was part of the natural order of the universe. Things are much better since I got busy and cleaned up inside the seat lug.
This raises some points. Apparently, this particular aspect of bicycle construction and finish wasn't seen as a priority back then, at least by some builders and mechanics. Was this more characteristic of racing vs. touring frames? or frames of certain brands or countries? I would suspect it all came down to the builder, regardless of the frame's purpose or country of origin. Or perhaps the builder assumed this sort of detail should be left to the mechanic who assembled the bicycle. Where or by whom were the Eddy Merckx frames built?
