Schengen is more about removing border controls so that EU can be more like USA in this regard. EU is about alignment with each other on common issues and resources like fishing waters, agriculture, trade deals, right etc.

They each have many implementation details, like if you are in EU but not in Schengen you don't have access to certain common databases.

The desire of countries cherrypicking and sovereignty made Europe very complex structure, I can't wait to have Federal Europe with every country in it with a simplified structure. Can be like US, can be like Switzerland or Germany maybe but thise structures over structures is just way too much and its begging for simplification.

Apparently, %36 of Spanish businesses haven't heard of the Schengen area and another %18 have heard of it but don't know what is it: https://europa.eu/eurobarometer/surveys/detail/3177
