And that's worth the numerous laws telling everyone in every state what to do? Just so you don't need to get a visa? (hint: I can travel visa free to places outside the EU/US, without prior authorization)
definitely not for travel exclusively, Eu citizenship gives you the right to move to any member country and do whatever you want for as long as you want (start businesses, get a job, retire, etc) -- no restrictions. as long as you can afford it of course.
edit: americans/canadians/australians and all other nationalities that can get in visa free are only allowed to stay for 90 days tops.
