Freedom and the feeling of freedom are relative.
As any law abiding citizen, we are only fee, if we obey the laws or don't get caught breaking them. If there were no laws it would be anarchy, and that doesn't work well, as people want standards of behavior enforced.
Think of it from a submissive in a TPE relationship point of view. They have a feeling of freedom because they submit to the rules the Dominant sets. The same is for any of us who function within a society.
So then within those laws, your question really becomes what laws would you rather not have, and still have a civilized society? Freedom of the press I always thought was pretty important, as is free commerce. Though we have restrictions on both of those in America. Freedom of the press is restricted by prohibiting certain groups or individuals from writing or publishing things that the government considers state secrets. Free commerce is restricted in that we don't want companies to be so effective, and so prominent that it tramples the chances for competing companies.
There are other laws that are restrictive that affect freedoms that we take for granted but don't think about. Gun laws, speed limit laws, traffic laws, it goes on and on.
