The UK can't possibly survive without the EU.... you know... like it did for hundreds and hundreds of years prior to joining.
It always depends on what you consider Survival.
Will the People Die ? Nope. They will Survive. They will lose some Wealth and have a Harder Time to make a Living in the Future. But its not like losing 10-20% of your Wealth would Kill you.
There is Countries where they got not even 10% of your Wealth.
Will the Union Survive ? Well thats already Questionable. The latest Events show an Great movement towards Seperation.
It might not happen right away. As the UK will attempt to prevent it. And might Succeed. But the Cracks are showing. And with the current Course of the Government of Suppressing Independence Movements their Support Grows. Making an Future Split even more likely. Thus the Union might actually not Survive this.
The British Economy ? It will Survive. But thats about it. It will Survive. But heavily reduced. Imports go much more Expensive for you now already. This will catch up to your Industry in time. And the UK due to being an Island is dependent on Imports. It cannot possibly sustain an Industry by its own Ressources.
And the only closeby Tradepartner is the EU. Meaning that with the EU now having Border Taxes you will have massive increase in Cost of your Economy Running.
Your Financial Sector ? Oh very Unlikely its going to Survive. The reason that the UKs Financial Sector had such a Good Time. Was because it had Full Access to the EU and thus as the English Speaking Country was doing all Financial Business for non EU Countries inside the EU.
But with Passporting Rights gone and thus Companies not being allowed to do their Business from the UK. This is gone. Meaning that the UKs Financial Sector will Shrink by more than 70% which is Devastating and comes around the same as total Annihilation.
If Companies were to oblige the Restriction they can do it from their own Respective Countries. And anything else will be done in the EU.
Even now Frankfurt, Paris etc are all taking Bites out of Londons Financial Sector. And your not even Out.
So well.
Depending on which part you mean. It might Survive of Course
Being a bit Poorer is not going to Kill you at least.
But if you really think that nothing bad will come from it. Your very Naive
