It's all relative. The Brits will always have their libertarianism, which is stronger than democracy, and is the true sovereignty.
Neither is true for modern GB, unfortunately. It's already turned into craziest implementation of multicultural socialist schizophrenia, which is leading its people to construction of just another caliphate. Its civil law long turned into no more than a veil for that disgrace.
You are right in the sense of ignorance and forgetfulness of British law. For example. If you were in a desert, dying of thirst, and there was a jar of pure water next to you, but you didn't know it was there, you might die of thirst. Or if you didn't know it was water, you might die of thirst. Or if you couldn't get the cover off the jar, you might die of thirst.
Brits (like Americans) have forgotten the basic premise of freedom. It lies in this simple thing: "Do to other people as you would have them do to you." This means that in bottom-line law, your accuser has to show how you have harmed him when he takes you to court. It also means, you have the right to accuse anyone who has harmed you of anything that you have been harmed in. The place to do this is Queen's Bench in Britain.
Did you ever hear of inflation? Inflation makes your money worth less today than it was worth yesterday. The banks pick up the inflation that you lose. Accusing the EU leaders of stealing your money value, by accusing your Britain leaders of not protecting you, makes them (your Brit leaders) liable to come to your open court, and testify how they are not stealing your value.
To do this, Brits need to focus their Brexit people in getting the proof, and then each of them find a government man/woman, individually, and accuse them directly, of the theft they are perpetrating. British Queen's Bench law states that whoever you accuse directly, must come to court and face the charges directly. If he/she doesn't, he/she is automatically liable, because by not coming, he/she is admitting guilt. If they don't come, get a judgment against the leader that requires repayment in the amount of 10,000,000 Pounds Sterling. That will wake them up a little. And you have your fellow Brexit buddies to back you up, because they will be doing the same. And, it is peaceful, done through the courts.
All this Brexit politics is simply a diversion designed to keep any real change from happening by focusing the people on emotional stuff, rather than focusing on doing something about having been harmed. The courts are open - Queen's Bench. This is stuff that Brits have been doing all the way back to the first Magna Carta, which is still alive as law in Britain. Why stop now?
