It's still important, it allows for demanded resources that aren't gotten in the right amounts or at all by a given country to be obtained from others.

It allows economies to thrive, and makes resources more plentiful and diverse, so that shortages are less lethal.

For instance, if the Irish potato plague had happened today, they could just easily get food from other countries.

It would be expensive, but they wouldn't have starved.
