"Except on topics of sovereignty, economics, immigration, trade"
Those are all points that are either unaffected by Brexit, or made worse:
1. Sovereignty. EU members keep their sovereignty. Yes, a few matters are delegated to the EU but (as Poland and Hungary are currently showing in an unpleasant way) sovereign powers are not removed.
1a. Since Brexit would make both N.Ireland and Scotland much more likely to leave the UK within a few years, the sovereignty argument rings pretty hollow anyway.
2. Economics. Every serious analysis shows that Brexit will be disastrous for the UK economy. Multiple industrial groups have started moving operations out; the others are begging the government for a very, very soft Brexit. These aren't commentators or academics: these are literally the captains of industry. If they're worried, I'm worried.
3. Immigration won't stop after Brexit: when we need workers, they will come. Most people don't come here except to work, anyway.
4. Trade. See point 2. If we lose all our free trade agreements overnight as well as losing free access to the EU market, our trade in both goods and services will not stop dead, but it will decline dramatically, the balance of payments will get much worse, the £ will collapse further, and the country will be impoverished. Do you think food's expensive now? Just wait for Brexit.
