sure they can , and its easy on an individual basis, but a little harder when extended families etc all decide to ignore the rule of law and just stay put.
we in the UK cannot sustain such forms of illegal immigration i am not sure if any country in the world lets you just turn up and stay.
First Nations people can travel freely across the Canadian-US border without documentation apart from proof of their native heritage. This is in recognition of the fact that their nomadic culture predates the creation of North America's borders and immigration laws. IMO, the Roma people (who are not necessarily "Romanian", BTW), are in a similar category and their distinct culture should be similarly recognized by European law. To advocate otherwise is to advocate cultural genocide, which I'm sorry to say went out of fashion along with the doctrines of manifest destiny and the white man's burden.
