Get real, man. Britain is a small country. Having open access to all of Europe gave Britain a great boost up economically. Brexit means going back to being a small country. They have the freedom to do so. That's what they voted for whether the pea brained "leavers" knew it or not, they were voting to shrink their economy. So, yeah, freedom is free and they are free to become a smaller economy. What's so hard for you understand about this?
Of course Parliament balked at shrinking the economy. So, now what?
