Of course you can, but when people identify themselves or others as "liberal", they're not referring to individual liberty, they're usually referring to "liberalism", which does contain some elements of individual liberties, but far more importance is given to free market economics and free flow of capital, than it is to individual freedoms. That's why corporations can invest anywhere and borders don't pose much issue for them, whereas it is very hard and expensive for individuals to move to another country.
