Technically it's easy to come around restrictions (for example, where I live, RT.com is fully censored "to protect me").
But from a lawmaker perspective, the topic is not technical.
The question, at the end, is about the enforcement of the punishments that go with circumvention; and in some places there is punishment even when you are "just" trying to circumvent these restrictions.
It's easy to break-in into someone's place. What prevents you from doing it, is the punishment (and potentially ethics), not the physical barrier.
