Presumably making people smaller would mean smaller brains. Given that communication inside the brain is easy, and communication between people is difficult, a larger population of people with smaller brains might be much less able to handle cognitive problems.
I was going to mention that as a limitation but it was already getting quite long.
I don’t think that kind of constraint would impose a very hard limit in the minimum size, judging from evidence like: most people with dwarfism have normal cogitative abilities, animals like crows have intelligences disproportionate to their brain size.
It’s still something to consider though and exactly how considerable a factor it would be could be an area for possible research. Could you make people pixie sized? for example.
