And no less centralised because the UK will now be ruled by one bastard government that cannot be trusted, instead of having the other 27 countries of the EU to moderate.
But it
is less centralized because the sovereign unit is smaller. If you do not like the current UK government, work to change it. The smaller the sovereign unit he more impact an individual can have on its policy.
By your way of thinking one world government would be best because then we would have 195 countries to "moderate".
Only if you think the individual can have any impact at all. In reality, the disassociation from the EU and in particular the cessation of the bill of human rights and the jurisdiction of the ECJ means that the fascist tory government running the UK will now be free to be as draconian as they like with nobody and no body able to intervene. The British voters will have the opportunity to change the government at the next general election, yes, but they've already shown that their judgement is flawed and I personally won't be eligible to vote in the next UK general election anyway. I'm waiting to see what happens and how my rights are affected by the negotiations, but there's a good chance I'll be changing my nationality in order to protect my own rights.
