I don't think this is a bad thing, to summarise things into a basic Pro/Con list, I have this:
Pros:
- Democratic freedom.
Not sure what you mean with that. Every country had their own governments making their own laws. Everything "imposed" by the EU was voted on by EU delegates each country voted for to represent them.
- Not restricted by EU regulations.
You're aware that most EU regulations already were established regulations for the UK law anyway, right? Furthermore, if you want to do trade with the EU, you'll have to abide to their regulations.
Plus, EU regulations heavily protected the lower and middle classes from the exploits of Tories and other right wingers who enjoy stripping away the rights of those particular classes.
- Don't have to pay billions of taxpayer money to the EU to prop up the weak countries.
Money which would go back into the British economy through trade agreements and weaker British areas such as Wales and Cornwall receiving funding anyway.
- No longer having to basically fund the EU themselves.
Wha? You are aware that the EU is not just funded by Britain, right? In fact, to my knowledge, the EU contribution of the UK is less than that of Germany, France and Italy. It also is the country with the absolutely least of its GDP spent on the EU among all EU countries (sans Croatia, I have no data for that).
(also mind you,
this data is a few years old, but it's still there).
No guarantee of that, and the UK already wasn't part of the Schengen area, so it already had border control.
- Some sectors lose EU funding, like science.
And whole swaths of the country losing funding as well, not only particular branches of the economy.
You also forget that this political isolationism might result in a heavy blow to the economy. The EU is the UK's biggest trading partner by far. Having virtually no borders between the UK and the EU meant that it was much easier to do said trade. And unless the UK is able to hammer out a very favourable agreement with the EU, trade will become much more difficult and expensive.
