Yes, that can be a problem for journal publications.

However, throughout the developed world, many academic, city, county,
and regional libraries offer their clients Interlibrary Loan service

and I even once got a loaned hardcopy book that came to Utah from a
library in Scotland (and was later safely returned to Scotland).
