No they are not. They are designed to prevent authoritarianism. The Weimar republic with all of its absolute, unqualified freedoms didn't work out that great.
Freedom is not defined by its consequences or its positive/negative outcome. Total freedom will of course devolve into a total shitshow but that doesn't make it not freedom.
Seing how freedom is a human construct, it makes sense only in context of the human condition. So treating it as something separate from outcomes for people isn't helpful.
Freedom for whom? Total freedom means freedom for the strongest. Laws exists to ensure there is more freedom for the weaker and less freedom for the stronger. They prevent a stronger person from doing something that allows a weaker person to decide whether or not to do something else.
I clearly said "when it comes to expression". There are many other ways in which Europeans are freer than Americans.
