Could you explain this?  Switching cost goes down with smaller feature size, so
why should it ever become prohibitive?

Of course, atoms are not all the same size.  The absolute difference in size is
tiny, but the relative difference may be several percent or more.  If you go
from molecular to atomic sizes, the difference can be an order of magnitude or
more.
