EU the increased the areas of supremacy it had over the UK law and has other member states with each subesequent treaty, it has control re some areas but not others.Well, if the EU did have supremacy over the UK - in law, as you state - you'll perhaps explain to me, how the UK engaged in a civil war until 1997, and how it went to war in The Falklands, Afghanistan and Iraq, without the explicit say so of the EU. But I'm sure you have further evidence to share that a "federal superstate" is being created, and you can provide examples of its potential reach.
We always were a sovereign state. You'll note that we didn't go out on a limb, once we found our "liberation" - we didn't bring back feet and inches, for instance. And we are still following EU regs just to trade with them, hence the huge rollover of EU law into UK legislation, pre-2021. Do you still feel enslaved by a foreign power, now that you can't remove a plastic top off a bottle?
These are the new areas of qmv between the nice and lisbon treaty

We rolled over EU law into UK legislation for ease of transition and cos others hope to push the UK back in, but as time goes on those laws can be updated/deleted as the UK sees fit and doesn't have to seek permission from europe.
If some of your laws have be set within the bounds of the laws set by the EU in those areas then you are not a sovereign state, if you can't see that then that's your 'problem' or you're just being disingenuous.
But it's immaterial cos we're not in the EU because thankfully the euro quislings lost and that is the bit that truly matters.
