This doesn't solve the problem because the vast majority of people don't "vote with their feet". To borrow a quote from the beginning of this article:

The human longing for freedom of information is a terrible and wonderful thing. It delineates a pivotal difference between mental emancipation and slavery. It has launched protests, rebellions, and revolutions. Thousands have devoted their lives to it, thousands of others have even died for it. And it can be stopped dead in its tracks by requiring people to search for “how to set up proxy” before viewing their anti-government website.
