ELI5: Why is the jugular so exposed?

Shouldn't such a central vein be more protected?

well the most important jugular vein that runs to your brain actually has some pretty good coverage,  the SCM lies right over it.  

as for the other jugular veins, they drain blood from places like your superficial face, head, etc.  so they're really taking blood right from the surface of your body, which makes them a bit difficult to cover up.
